Hello girls. My son is 11 months old and he really wants cottage cheese. We buy good Bio yogurt at the store, with 3.7% fat content. I haven't given him any cottage cheese before, only Hipp yogurt. So I wonder if it's okay to give him our cottage cheese or should we buy baby food? At what age did you start giving your child dairy from the general table?
