My 2 months baby cries a lot while taking feed. I always take out the burp even then she cries like having a lot of pain. At times she will be very hungry but as soon as after 2 3 sips she pushes away the spoon or the bottle and cries in hunger. We give her colicaid as well. The doctor says it's normal upto the age of 4 months but it's affecting her intake as well. We have even started protectis 2 times a day. What else can be done.
