My daughter will be 3 months on the 22nd. My boyfriend already wants to give her oatmeal cereal cause he thinks my daughter isn't satisfied with her milk cause she's hungry every two hours. I heard you aren't suppose to give babies cereal at least 4-6 months. But I know other moms that gave their babies cereal at 2 or 3 months and their baby is fine. What do you think I should do ?
