I feel like such a shit mom right now. My baby has had bad diarrhea for about a week now and throwing up occasionally. I kept taking him to the doctors and all they kept saying was it’s probably a cold. I know what the hell is wrong now🤦🏻‍♀️ It’s because I changed his formula! I changed it two weeks ago because my husband asked that I try a different kind. I should’ve listened to my instincts and said no because now it’s messing with my baby’s tummy!😭 I’m slowly weaning him back onto his old formula, I pray he feels better within a week or two 🤞🏽 if not, back to the doc we go.
