Will feeding my baby with formula then switching to breast milk and then back to formula cause my baby to have diarrhea?
yes very possible its too much for the stomach being that formula is harder to digest than boobie milk
The formula may have caused it. Not all kinda agree with all babies. Some parents have to switch to countless brands before findin one that works with baby.
So, my baby is 3 months and she's on 1% milk. Formula doesn't sit right with her at all.

My baby is a prune!! What fruit is your baby this week?!
How many ounces of formula is it ok to give my 1 month old?
When did you moms start giving your baby oatmeal? My baby is 2 months 1 week & I’m gonna start giving him a little oatmeal with his formula in the morning & at night!
My baby is refusing formula yet again... my nips are going to fall off
I did both my baby was fine
