it's very normal for babies to spit up a bit. try not to overfeed ur baby. keep a gap of at least 2 hours between feeds. and see if that makes a difference. try to feed in a more upright position. and if your milk production is too much maybe ur baby is taking in too much at a time. try to hand express some milk out before feeding your baby.

this is a common problem in babies. it is because of the reflux. don't worry it will go away after a few months. Also there is nothing as the baby doesn't like mother's milk. please ignore all those and continue to do as you are doing now
