what's the earliest you ladies gave your baby cereal? do you start on rice or oatmeal? it just seems like formula isn't feeding/ filling my son up anymore. my mom said she started feeding me and my sisters cereal from the bottle at 3 months & my son is 3 months and 1 week. i want opinions and thoughts! & i looked it up and it seems like a ton of people start earlier than 4 months, so i'm curious!!
