More skills should be unlockable for kids

Children can learn singing if they max out their creativity skill (they can also learn pipe organ). Programming with simple kids programs would be possible (I programmed robots in my childhood). Writing should be able to go up as they can write in their journal (which usually increases their writing skill) and write dollhouse stories on their computer if they play with dolls. Photography should also be able to go up (but I don't know if it does). Parenting skill is something even teens cannot max out. Only adults can develop this skill further.
Bowling skill is one of these skills children can learn immediately without needing to max out any of the children skills. It would have been great if motor skill was maxed out first. Painting skill should be in for children. They were able to paint using the easel in the previous games.
