My 2.5 month old baby was born prematurely and is having to take supplements-
Calcium, Multivitamin,Iron and vitD. Also, HMF. Which is why i had been feeding her breastmilk by expressing it. Since her feed demand increased, I have introduced formula milk also. I am combination feeding her with atleast 20-25mins of burping.
I have observed today that she is crying on and off during and after feeding. That remains the case while burping and sleeping as well. Also, this crying is different from hunger cry and discomfort cry. It seems as though she is pain.
Please suggest if there seems to be any issue or if this is normal.
