Baby weight?

Megan

Hey everyone! So my baby is 20 weeks old and had his 4 month old check up the other day. They said he is gaining weight pretty rapidly but I don’t know how to feel about that or fix it.. they suggested continuing the formula but maybe add in some purred foods but I’m not sure how that would change things.. I guess my question is how much are your 4 month olds eating and what do they weigh?

Sorry my post is all over the place I’m just confused and think my lil man is okay
