My baby fusses or cries during nursing – what’s the problem?

Some babies will fuss, cry or pull off the breast during nursing. There are a number of reasons why this might be happening. It’s pretty common to see this type of behavior at around 6-8 weeks, though it can occur at any time. If your baby is generally fussy (not just when nursing) see My baby is fussy! Is something wrong?

Determining the problem
Here are some of the problem-solving steps I go through when my baby is fussy at the breast or a mother asks me why her baby is fussing during nursing:
How old is baby? Most babies go through growth spurts during the first few days at home and around 7-10 days, 2-3 weeks, 4-6 weeks, 3 months, 4 months, 6 months, 9 months, etc. Many babies are fussy during growth spurts.
Is baby working on anything new developmentally? Babies who are starting to notice the world around them can be notoriously distractible. Any kind of new developmental step that baby is working on can affect nursing temporarily, whether it be fussy nursing behavior or simply more frequent nursing.
When is baby fussing? To figure out the cause it’s helpful to pay attention to when the fussy behavior happens, both during the nursing session and during the day.
If baby is fussy right when your milk is letting down (or immediately after), there’s a good chance that the fussy nursing is related to a fast let-down. If baby is fussy before let-down, or a few minutes into nursing (and a while after let-down), then baby may be impatient for the fast flow of milk that comes with let-down. Fussing at the end of a nursing session (or what seems to be the end) may mean that baby needs to burp, or is ready to finish nursing, or just wants to suck (and doesn’t want to deal with a new let-down at this point), or wants to continue nursing on the other side or with a faster flow of milk.
If the fussy behavior is mainly in the mornings, it might be due to a faster than usual let-down if baby has just had a longer sleep period and mom’s breasts are fuller than usual. If baby is fussier during evening nursings, it may be due to the normal fussy time that most babies have during the evening. Although most babies don’t react to foods that mom eats, some do. If you eat a particular food at about the same time each day (or most days) and baby has a regular time where she fusses during nursing, try not eating that food for a week or two to see if things improve.
Does fussing occur on both sides equally or only on one side? Most moms have a faster let-down and/or a more abundant milk supply on one side than the other, so if your baby fusses more on one side, it may be due to these differences.

What else is going on with baby? Is she sick or teething? Is something new or different going on in her environment? Has she started solids or is she trying a new food? Is she exhibiting other symptoms besides the fussy nursing?
Below are discussions of some of the different things that can lead to fussy nursing behavior. Keep in mind that the problem may also be a combination of several things.

Does baby need to burp?
Many babies will cry, fuss, pull off the breast, etc. if they need to burp. Try to burp between breasts and after a feeding, but don’t worry if baby does not burp and is content. Breastfed babies overall don’t take in as much air during a feeding as bottle-fed babies do, so usually don’t need to burp as often. If baby has been crying before she nurses, or is so hungry that she nurses “frantically” or if mom has a fast let-down, baby could be taking in more air and may need to be burped more often.
Burping is usually only necessary during the first few months, though it may extend longer. Once your baby is moving more freely, she will be able to relieve the gastric gas herself. This usually will occur between the 4th and 6th month, but may be shorter in some children and longer in others.
If baby has a hard time burping, try burping more often during a feeding. The best burping position is one that applies firm pressure to the baby’s tummy. Placing baby over the shoulder way up so that there is pressure on baby’s abdomen often works well. Walking around while doing this might distract her long enough to get a good burp. You may even want to lie baby down on her stomach and burp her that way.

Growth spurt
Babies often pull off and fuss during growth spurts. Most babies go through growth spurts, sometimes called frequency days, during the first few days at home and around 7-10 days, 2-3 weeks, 4-6 weeks, 3 months, 4 months, 6 months and 9 months (more or less).
