Mommies, how do you feed/supplement your babies? I introduced purees at 4 months, now we're 6 months old, I give them porridge in the morning, puree for lunch, and can offer a cookie as a snack sometimes, but mostly breastfeed. Sometimes it seems like the baby is hungry, or am I wrong? Can you tell me how to feed them properly and what?
