What to do about 9 year-old's sleeping habits?

I don't think you need to make bedtime later or put up with early starts. Just tell him he has to wait to bound into your room until 7 am and make sure he has books to read, or Lego to build or whatever will keep him happy in his own room until then.

A small bribe for a week of not waking you up might also help

Agree that by the age of 9 he should be able to amuse himself quietly in his room until 7am. Has he got a clock so that he can see when it is time to get up? Waking at 6 is quite normal at his age, but he shouldn't need adult company as a matter of routine.

If you use the 'bribe' idea, which I think is a good one, make sure you set it up in discussion with him and let him choose what the treat at the end of the week should be (though you can veto any unsuitable choices!)

At 9 your son is at an age where he should understand what time would be acceptable for him to get the household up, get him a clock and until the decided time he can read or play in his room.

It's more than reasonable for a 9 year to stay in his room until 7am. The clock in his room could be an alarm clock that he is taught how to switch off. He'll soon accept that he doesn't wake you until his alarm clock goes off at 7am. Once this new pattern is established, I'd turn the time on his alarm clock back by at least 15 minutes.

I agree with the other comments - get him a clock! When our children were small we put a timer on the light switch. When the light came on then they could come into our room but until then they could read or play quietly in their room.

At 9 years of age you would think he would relish the idea of an hour or so to read a good book and not feel the need to raise the whole household to keep him company.

...and put a bolt on your bedroom door!

I agree with all the suggestions about a clock and a fixed time when he may enter his parents' bedroom. By the way, the problem is not a 9-year-old's sleeping habits but his waking habits.

Can he tell the time? If so then tell him what time he can come into your room. Leave something enticing in his room for him to find each morning- doesn't have to be expensive - and he will be busy until you want to get him ready for school.

If he reads, then what an marvellous time for him to read - he'll soon be miles ahead at school.
