Hi , Why my 4 months old daughter is spiting out the milk after few minutes of breast feeding?

A. hey hey mommy few things could be the reason. is he only on breast milk or formula as well. make sure there is a gap between the two feeds. do not over feed. Also give tummy time atleast once a day. also burp after every feed even if he falls asleep. also make sure you don't put him in a lying down position immediately use a pillow and keep him elevated for a bit.
