Hello! I am exclusively breastfeeding my 3.5 months old baby. Sometimes he just gets fussy at the breast as soon as I Latch him on. Is it because of slow let down. Or is it because my milk supply is low.please suggest .

A. Some babies fuss when they are having a growth spurt, or when they are having trouble dealing with a fast milk flow. When babies are really upset, it can be hard for them to calm down enough to breastfeed. Of course, there are situations when this fussiness is a cause for concern.
