Hiya moms. As I said before, my baby is transitioning from breast milk to formula at 8 months. I'm slowly increasing the ratio of formula to BM over the past week. The most we've done so far is 1/3 formula... but the constipation is worrying me. I bought several formulas that were supposed to be good for constipation. (He's currently trying Similac sensitive.) How long do I experiment with different formulas? How long should I wait to see if his body naturally adjusts with the formula he's drinking? (I'm also giving him lots of puréed prunes, pears and baby oatmeal.)😦
