My oldest (girl), 7, I think she will need help with that up until 20 or so. She is so scattered brain makes me go insane.
My next one (boy), almost 5 does not want to get down from his seat until he finishes whatever he started (coloring page, logic game, drawing, mazes, or whatever).
The other don't know yet. I am still trying to handle lots of things while sitiing down by my oldest, or keep checking in with her every 2 minutes.
