Hello toddlers can do many things such as play hide and seek or cuddle just like babies.. And just to anserw everyone's question, baby's will grow at some point in to pre-teens, and that age is like 11 or 12. Like most people i thing it should go like 8-year old, pre-teen, But you need to unlock babies before you can get toddlers teens,etc. Hope this helped comment if did!
