Phil- “A child must be mature enough to keep track of time even when they are engrossed in playing.”
How old a child has to be to look at his/her watch once in awhile, eleven? I would say if you believe a child can’t look at his/her watch until eleven, try the alarm watch. I think kids know from around nursery/kindergarten what it means when the bell in school rings. Just like in school there is some sort of consequence for tardiness after the bell rings, so too at home there should be some sort of consequence for not coming in on time. It’s easier to blame neighboors and everyone else than being a good parent!
