I would put him in bed at about 7.30pm so he is def asleep by 8pm. Lots of stories and low key stuff to get there - my DS isn't too bad when OT but DD gets very hyper
. Books is often the magic to keep them both calm.
Regrading the nightlight - again I really think being woken by it is a novelty thing that will go away. Just like if you moved house and there was a bit more noise and light coming in the window. They honestly do adjust, just that we try too hard to help them
. We moved to a house on a main road last year, DS sleeps at the back so he isn't disturbed (he is my EWer), DD sleeps on the front where the traffic starts at 5am and the sun rises in that direction as well. Makes no difference at all after the initial 'getting used to it' bit. I've recently been sleeping in the spare room at the front (because DH is snoring and driving me crazy!), and after about 6 weeks or so I have stopped being woken by traffic noise as well (I was waking and then nodding back off again).
Also as you shift the wake up the need for food/ have a wee etc will adjust as well. Make sure you do a milky drink or supper if tea is pretty early currently.
If I was asleep with DS there is no way he would sleep past that initial stir either!!
I did have to be pretty firm about not ignoring the fro-clock. Yes, it is understandable that they don't want to self entertain for 1.5hrs, but if you seriously want them to follow it you have to follow through regardless yk?
School will help a bit I think. DS was still very prone to EWs, but especially towards the end of term would tend to wake at around 6-6.20am after a 7pm bedtime. Less so towards the end of the year, but my DS is almost 6 now so to be expected really. He needs 9.5-10hrs of sleep a day, more like 10hrs when you add school in. DD who is 4 and a bit is more like 11.5-12hrs. DS has never ever been beyond 11hrs though, even from nap drop at age 2.5.
