Wondering what breastfeeding/chestfeeding look like when your baby is 6-9 months? As our little ones continue to grow physically {begin to roll over, sit up, crawl} and developmentally {sleep longer stretches at night and interact more with the world around them}, we notice the impact of these changes on their feeding patterns.

In this blog series, Breastfeeding the Older Baby - What to Expect and How to Adjust, we will answer some of the most common questions and concerns we hear from parents, as they navigate breastfeeding/chestfeeding a 6-9 month old. What are some normal behaviors to expect from a baby this age and how can you tell if there’s a challenge that you should seek lactation support for?

What does breastfeeding/chestfeeding look like in months 6-9?

How often should a baby be breastfeeding and how long should feedings take?

At 6-9 months, breastmilk is still a vital source of nutrition, even as your baby starts to explore solid foods. The frequency and length of breastfeeding/chestfeeding sessions may vary depending on your baby’s appetite and routine, but here are some general guidelines:

• Breastfeeding frequency: Typically, babies breastfeed/chestfeed around 5-6 times per day at this stage, with some babies still nursing in the middle of the night, as well. 

• Duration of feedings: Babies at this age can be very effective at removing a lot of milk in a very short period of time.  Each nursing session may last anywhere from 5 to 20 minutes (on average), depending on your baby’s efficiency, interest, and when they last fed. 

• Feeding positions: As your baby becomes increasingly mobile, you may notice that they may want to move from the cradle hold to sitting or standing or some variety of nursing gymnastics.  Handing your baby something soft or crinkly to play with while nursing may help them focus and stay in one position until they are finished feeding.

My baby is eating solid food now, how does this impact our breastfeeding/chestfeeding routine?

Introducing solid foods to your baby’s diet can shift your breastfeeding/chestfeeding routine, but your milk continues to be the main source of nutrition. Here’s how solids may impact your feeding routine and how to protect your milk supply in the process:

• Complementary, not replacement: Solids are meant to complement your milk at this stage, not replace it. Continue to breastfeed/chestfeed (or offer a bottle of your pumped milk) before solid meals to maintain milk intake.

• Keep serving sizes of solid foods small: The goal for solids between 6-9 months is to familiarize your baby with different tastes and textures, while also developing hand-eye coordination, as your little one learns to self-feed.  Keeping serving sizes small will ensure that your baby will not fill up on solids and continues to take around 30oz a day of your milk by breastfeeding and/or bottle. 

Ensuring milk production: To keep your milk supply stable, continue breastfeeding/chestfeeding on demand and ensure regular milk removal through nursing or pumping.

How much weight should my baby be gaining at this age?

After six months of age, normal weight gain for a breastfed/chestfed baby is 2-3oz per week. Weight gain slows during this time as babies begin to roll over, scoot, crawl, and walk, burning more calories by being more active throughout the day. If you are ever concerned about your baby’s weight gain patterns, you can reference theWHO growth charts, which were created specifically for breastfed/chestfed infants.

My baby keeps biting me while breastfeeding/chestfeeding.  What can I do to stop this?

If your baby is biting while breastfeeding/chestfeeding, it can be painful, but there are ways to gently prevent and correct this behavior. Here are some tips to help stop biting during feedings:

• Watch for signs: Pay attention to cues that your baby may be done feeding or about to bite, such as decreasing swallows, adjusting their latch, or giving you a smirk like they are about to do something to get your attention. If you see one of these signs, immediately unlatch your baby before they have an opportunity to sink their teeth into you.

• End the feeding calmly: If your baby bites, immediately stop the feeding and calmly but firmly say "no biting" or "that hurts." This helps your baby understand the connection between biting and the end of feeding.

• Offer alternatives: Babies may bite when teething or exploring new sensations. Offer a cold teething toy or a chilled cloth before or after nursing to soothe sore gums.

• Stay consistent: Respond the same way each time your baby bites, using calm but firm guidance. With repetition, your baby will begin to understand that biting interrupts feeding.

Help a Mama Out: Dealing with the Biting Breastfeeder

Oh, that sweet infant gummy smile!  So serene.... so innocent.... so adorable.  But all toothless mouths must come to an end and teething starts another fun developmental stage for your little one.  Teething can also stir up some anxiety in the breastfeeding mama, which we are hoping to aleviate today.

Will my baby bite me?  

Do I have to stop breastfeeding?  

Most moms have felt a clamp down on their nipples from their teething babes once or twice, but it doesn’t mean that your breastfeeding relationship has to come to an end.  No need for those new teeth to be a deal-breaker!

We turned to the wise breastfeeding mamas on Facebook to offer some tips for dealing with a biting breastfeeder.  As always, your advice was amazing.  Here is what you had to say.

Top Tips for a Dealing with a Biting Breastfeeder

Stacy: Remember that your baby isn't malicious and isn't trying to hurt you. If baby bites at the beginning of a nursing session, try giving him/her something cold/hard to chew on beforehand. If it's at the end, pay close attention and break their latch as soon as they finish eating but before they are tempted to play with the new sensation of using their teeth.

Amber: Remember, it’s just a phase!

Michelle: I found that using a nursing necklace was really helpful.  Instead of pulling back on my nipple when he distracted, he would play with the nursing necklace while breastfeeding and focus on feeding.  I found that he mostly bit down when he was distracted.

Liz: Ugh. Cry? I do the "don't bite. That hurts." And set P on the ground for a few minutes. Then nurse again.

Katie Jo: What ultimately worked for me was to pay close attention and learn to recognize when he was finished eating. Then I would have to quickly unlatch him with my finger before he started to play/explore what he could do with his teeth. If I didn't catch that moment quickly enough, he would bite down the instant he sensed I was about to unlatch him, and my nipple turned into a rubber band chew toy for him. Sometimes he would bite my finger instead. I tried pressing him into my breast and telling him ouch in an upset voice, but he just laughed every time.

Julie: I bought my daughter an amber necklace to help relieve some of the teething pain she was feeling.  Less teething pain = less biting while breastfeeding.  I also wore one around my neck as well.

Jen: I tell P, "ouch, that hurts mommy." She stops biting/nursing and looks at me with concern. I let her know it hurts and to be gentle. Sometimes it takes a few reminders, other times she will stop.

Stephanie: If your child will take a cold teether, try offering that before or after a nursing session.

Tamara: Be patient, they may be in pain from teething and doing their best to find relief.

Jennifer: Keep your finger close by their mouth so if they go to bite, you can stick your finger in the side quickly to get them to unlatch!

Erin: I loved the Camilia teething liquid to help with teething pain.  I would use this a couple of times during the day when my baby was really teething badly and I thought it really cut down on the biting while breastfeeding.

Kat: My kids didn't start that nonsense until they were 10 and 8 months old respectively. So every time they bit, I would quickly unlatch them and set them down. I would say "no biting Mama" and ignore them for a minute or 2. My daughter figured it out after a couple of days, and my son took a week. I tried a couple of times to do that thing where you push their nose into your boob to make them open their mouth but it's so counterintuitive! The first instinct is "get it off me!"

Kim: My 9.5 month daughter got her first teeth at 4 months 1 week. She usually bit me when she was done eating or not hungry. I would tell her no biting and take her off my boob. I would make sure when she was done eating to immediately unlatch her or that's when the biting would begin. I could tell when she was about to bite. Now she is biting my shoulder.

Baby Jaws - Breastfeeding a Teething (or Toothy!) Baby

Duh Nuh Duh Nuh………….Duh Nuh Duh Nuh. (come on, you know you just read that out loud).  

You know they’re coming.  You’ve heard all the severe warnings from well-intentioned friends and family.  You’re scared of what’s to come, but know you’ve gone too far to turn back.  Shark-infested waters, you ask?  Noooooo - a breastfeeding baby who has grown TEETH!  

Somewhere around 6-8 months (sometimes earlier, sometimes later), your baby’s first tooth will erupt.  This is most likely an event you will celebrate, both because of the milestone that it is, but also because it may be a temporary break from the cranky, drooly, mouthy baby who replaced your own sweet one a couple of months back.  There are lots of symptoms that point to teething, but the most common ones are: red and swollen gums, increased irritability and drooling, sleep disturbances, and low grade fevers.  Your baby has most likely learned that chewing or gumming on items helps ease the pain and will try to cram everything within reach into his/her mouth.  As that tooth begins to emerge, there may be some small worries creeping in on your excitement about this next stage.  What will it be like to breastfeed a baby with teeth?  Will my baby bite me? Some moms will find that they do start to feel the baby’s teeth while nursing - baby may scrape teeth across nipple when latching or delatching.  And yes, sometimes the baby will bite.

Why did he bite me!?

Short answer is that it’s not because he doesn’t like you!  New teeth bring a whole new sensation for baby.  He may want to explore his world using his new teeth and will scrape and/or bite items that come into his mouth.  Another reason that your baby may clamp down onto your nipple during a feeding is because of teething pain. As mentioned above, babies learn that biting and chewing on items may offer them some relief.   If they are experiencing teething pain while breastfeeding, they may try to alleviate that pain by biting down.  Or, your baby is finished with the feeding and wants to play!

Note: Sometimes when persistent nipple pain starts when the top teeth come in, it can be caused by an unresolved upper lip tie that is causing the baby’s top teeth to scrape against the nipple.  Make sure your baby’s upper lip flanges out, like fish lips, to prevent this pain, or consider having his/her upper lip tie revised.

What should I do?!

Almost all moms will have the same reaction the first time their babies bite them while breastfeeding - some loud yelling and possibly a quick change of position!  This is a completely normal and expected reaction, but you may notice the sudden sound and movement startles your baby.  The best thing you can do is soothe your baby and resume the breastfeeding session.  If your baby should bite you again, calmly remove the baby, give them a quiet vocal command (‘no’, ‘that hurts mommy’, etc) and temporarily end that feeding session. If your baby is still hungry, then offer the breast again to finish the breastfeeding session.  

Also, some moms find it helpful to rub a cold, wet facecloth on baby's gums before latching to desensitize the teething pain before latching.

Because of the sucking mechanism babies use when breastfeeding, it is impossible for them to actually remove milk from the breast when they clamp down on the nipple, therefore biting may indicate baby isn’t hungry enough to feed.  This is clear when a baby will bite towards the end of the feeding.  One way to prevent this is to watch your baby while feeding, and when he/she starts to show signs that he/she is almost done (suck pattern will slow greatly, baby may come off often and smile and interact with you), calmly remove him/her from the breast and end the feeding session.  

For almost all breastfeeding babies, this biting is a temporary phase.  As they grow more accustomed to their new teeth and learn that biting means the breast is taken away, they will likely stop the behavior.  If your nipples become cracked or sore because of any biting, we recommend applying organic coconut oil - it is soothing along with having antibacterial and antifungal properties.  

Rest assured, the biting is normally a very fleeting behavior.  Before long, the waters will once again be safe to enter.
