He is still very young. And that can mean not mature enough for our expectations sometimes or how we would like them to be at a certain age.
Even at age 10ish I remember having to be very specific with my kids about clean up projects unless it was more broad like vacuum the carpet in the family room or feed the dog his scoop of fod. Is he the kind of processor like Meg described that would do better with a list?glad he got it done in time.
