DDs turning 4 and 5 next month go to bed between 7.30 pm and 8pm each night, although if we've had a huge day or they're sick, overtired etc I'll get them in bed more like 7pm. They wake anything from 6am to 8am - 8am obviously being on the mornings when they actually HAVE to get up!

DD2 could still benefit from a day sleep on some days, especially after a couple of full days in a row at kindy, but if she has even 10 minutes sleep she is still awake at 11pm so I more encourage quiet time than sleep.

TBH I don't find their bed time really impacts on their wake time. There have been a few occasions where I've thought geez I could do with a sleep in tomorrow so if its a non-school day I'll let them stay up to 8.30 pm or even a smidge later. If anything, they wake earlier.
