Hi ~ I was just curious about something. What do you do if the baby self-weans before they are 12 months old? (Let's say around 9 months). I hope that my baby will continue to bf until 12 months, but I was just thinking that I hear of a lot of babies self-weaning around 9-11 months & was just curious what do you do? I know cow's milk is a no-no until 12 months, & to start formula at that point seems odd (and not sure if a baby would take to it).
