I usually burp baby after feeding 40 ml of expressed milk..what I observed today is he is spilling out plain milk with each burp and that too in more quantity..What can be the possible cause of it?

If it's not curdled then it's coz of overfeed..; give smaller quantity and check.

It is not over fed for sure...can there be other reasons for it?

And what if it is curdled milk..? At times he removes curdled milk as well..what is the reason for it?

If you think he is throwing lot of milk please consult pediatrician. It can be reflux or gas which is common in babies. Try holding your little one up for as long as you can like 10-45mins from feed. Try keeping his upper part of the body little elevated while sleeping like giving an extra layer of bedding only for upper half. Also gettle give cycling movement excercise with legs helps in digestions and removes gas. I understand you don't feel good when u see your baby throw up. Try all this if it persists please consult doctor.
