Anyone else's LO do fine with normal food when they were at that stage but their stomachs completely rejected baby food and suffered from stomach pain and constipation? My LO, when we gave her baby food, howled in pain a few hours after and kept up with the discomfort for a few days. She wasn't able to poop, either. We give her normal food and she's completely fine, her tummy is fine, and she sleeps shortly after. She passes stool normally and sleeps better. Anyone else's LO's tummy reject baby food and baby cereal?
