Toddlers: Do you max all their skills??

Not always, but quite often I do. It's not difficult, so sometimes the toddlers max out the other skills on their own except thinking skill (on long life span they do max thinking too). I often only help them to max the thinking skill at first and let them do the rest of the skills by themselves.
It also depends on the toddlers, if I don't have any specific plans for them I just let them do whatever they want.
