We have EXACTLY the same thing going on here!!!
DS is 2.5 and DD is 5 months.....(she's still in with us)
DS is a DREAM at going to bed ..all thanks to BW I might add!! HOWEVER....
Transition to big boy bed was a sinch..over Christmas lots of travelling in UK, lots of different beds..had the same pillow and quilt with him and he was an angel...got back home, bought him bed straight away...and he was chuffed to pieces!! (Especially with his Spiderman duvet set!! Boy they grow up so quick!!) Anyway I digress....
He is still great with going to bed (7.30), settles straight away and has been sleeping until 7.30/8 then last week we went away for a few days staying in a hotel 'family room'....AND he had a huge coughy cold which was waking him up....so now we're back and he's out!!
He's waking at anywhere from 5.45 onwards.....
We've always completely shut his door..one good thing is I hear it the second it opens so I'm out to greet him before he comes into our room.
I also think..just by having talked to him and explaining we need our sleep...he hasn't got out of bed for a few days now, but still wakes up crying and calling for me. So this morning knowing that if I took him out of bed he'd never get back in again, I said I'd just sit on the floor til he was alseep. Almost got away with sneaking out once...but he 'caught' me
...so back I sat. I then said I was cold so I was going to get my dressing gown on...to stay laying where he was and I'd be back...I hovvered by his door for a short while then, when I couldn't hear him trying to get out, went back to bed. He did go back to sleep thank goodness (was up 6 times in night with DD who has bronchitis at the mo!! so kinda need a few zzz's!!)
I'm going to see how tonight pans out...
his naps at home have been a bit erratic lately too....he used to be dead good at these.....it really doesn't seem to make much difference for his night-times ..some days he naps like clockwork 10.30 - 12.30, other days he refuses to and goes to bed at night flagging big time...still 6 am wake up call.....
One thing I was thinking of doing if it carries on, was getting him a not very loud alarm clock (if there is such a thing...) making a game out of it but setting it for 7-7.30am and saying that only when he hears this can he get out of bed........
Sorry I've droned on....really interested to find out what tips anyone else has...
