How can I stop Ds waking the whole house every morning ?

[nutcracker]

He is 3 and since he has gone into a bed, he gets up every morning and goes straight into the dd's rooms, switching their light on and waking them up.

Dd1 is getting peed off with it now, this morning it was 6.00am.

I tried putting a gate on his door but it doesn't fit very well so I had to take it off.

Have tried saying he can't come out until someone calls him, but that doesn't work.

Help

would he understand a star chart/reward system at this age?

is the door shut already?
What about turning the handle to other way without him knowing?

Are his toys in his room?
Favourites toys in there if there not...

Get the gate fitted properly if nothing else works.

turning the handle=unscrewing the whole thing and swaping them over so that it goes up to open and not down

Could try the handle thing yeah.

Star charrt wouldn't work I don't think no.

He has all his toys in there but he just wants to see everyone the minute he wakes.

Would one of those bunny clocks work do you think ?
