Re: Low supply?
This sounds very normal for 3 months.
One thing that can happen when supply adjusts, going from overabundant to just right, is that babies start to fuss at the breast. The baby got used to letdowns happening almost immediately, requiring little work on the baby's part. All of a sudden, it takes longer to get a letdown, and baby gets impatient. It's like she has to learn to nurse all over again... And that makes her mad! Best thing you can do is ower through it and let the baby learn how to become a better, more efficient nurser.
