Colic babies

Feeling stressed up as my baby wont accept formula milk. Its the 3rd formula we bought n baby vomits merlion after drinking it.. my nipples hurt so bad cos its like latching & pumping 24/7. I have no rest & my c sect wound is hurting again. (Its been a month) i dont know what to do. Doc gave ridwind to get rid of gas.. ive been doing bicycle exercises & giving her massages with ointment... anybody face the same problem? Its like i give milk... she sleeps... but then keep waking up n crying2.. n i hve to carry her n its on repeat. #firstbaby #1stimemom #advicepls
