Q&A: My nursing baby cries at the left breast and not at the right. Why?

by Marie O'Sullivan, RN

My 3 1/2-month-old baby used to be the best nurser, but now he cries at the left breast and not at the right. I do not understand why. I know there is milk coming from that breast as I check often. Any ideas what might be going on and how I can help him nurse from both sides?

It is not uncommon for babies to develop a preference for one breast. Your little one may feel more comfortable being held at the right breast. I would try different holds with the left breast during your feedings (try the football or side-lying holds). Also, try offering the left breast first. Maybe he will latch on better if he is hungry. Be persistent—this may only be a phase. If everything else fails, you can feed him from the right breast and pump the left for awhile—but remember to always offer the left breast as his preference can change again.
