my baby is 1 month old and is on formula feed. from yesterday i feel she is having sour eructations. she cries aafter burp. what should i do

Formula can cause that. Any reason why you have to give formula and not breast milk ? Breast milk is the most easily digestible food for a baby under six months of age and it also offers a lot of immunity benefits. If you need help with getting breast feeding going then do meet a Lactation specialist.

i have a low milk supply. i m expressing milk and giving her but even after one hour of pumping i hardly get 10 ml thats why i m feeding her on formula :( can you please advice any lactation specialist in east delhi.
