My little guy is just 9mts and he'll only have 1 day sleep. It's not even a long one normally, on a good day we'll get 1 1/2 hrs, yesterday we got 40mins! BUT.... he goes to bed around 6:45pm in the evening and wakes up around 7:30-8am every morning, 9 times out of 10 he'll sleep through, we get the occasional wake up for a cuddle or 'bonus boobs' but that seems to be only when he's teething.

I worry that he doesn't sleep enough during the day, but he's not grumpy, he's perfectly happy, rolling and commando crawling, playing with toys, his brother etc....

Go with whatever works for you I say!
