Sleep

Hi guys

I was wondering.. At what point is it "too much" sleep?

My 18 month old slept from 7:30pm to 11:30am.

I know from his diaper he hasn't been up at all. It's empty.

We allowed this because we both work nights and I went to bed at 2am and had to be up by 5:45am exceptionally for my stepson. We (husband and I) were toasted and could use some extra sleep. (we often use the baby as an alarm clock to make sure we get the most of our sleep)

He usually sleeps between 9pm and 9am, so he's a pretty decent sleeper. He went to bed earlier last night because he had been up since before 7am and hadn't napped, so he was tired, and one of my other stepchildren has a bedtime at 9pm as well and since they share a room that didn't go well the night before.
