Hi Donella!

I would definitely try and cut down to 1 day sleep. Louis is only on 1 now and he sleeps much better for it. If he has two then he's up until at least 9pm and ends up a grumpy mite.
When we first started to cut down to 1 (a couple of months ago) he would be quite grumpy in the late afternoon but we just put him to bed by 6.30pm and he still slept through to around 7.30am!
Now it suits him so well. In the beginning he'd go to bed at around 10.30am and now it varies from around 11am - 12pm.
Might be worth giving a go because it would drive me nuts having him play around so much - especially at night!
Good Luck!
