So my daughter is 11 weeks we have been in and out of the drs office because of her colic and fussiness from colic thinking maybe its a milk intolerance. Last Thursday the Dr switched her milk to similac hypoallergenic milk, which seemed to help a bit but the last couple days she's been throwing up more only to find out today at the drs she's gained 11 oz in 4 days!!! Which is insane I only feed her 4 oz ever 2 hours sometimes she doesn't even finish it. Anyway the Dr didn't seem too concerned just said to try and give her 3 instead and that maybe that's why she's been throwing up. She changed her milk again to a more advanced hypoallergenic formula for 3 days and changed her acid reflex meds too. I'm just feeling overwhelmed I just want my baby to feel better, I feel guilty for possibly overfeeding but its hard to tell when she's hungry when she cries all day. Just hoping things figure themselves out and soon.
