At what age did your baby sleep through the night?

[GingerMaman]

Just that really, at what age did they sleep through?

I've got a 9 month old and can't wait till that day comes (if ever). Currently on hourly awakenings so need some hope ...

DS1-3.8 years. Not months, years. I thought he was never going to get the hang of it.

DD-6 months.

DS2-still waiting at 13 months. He's shaping up to be an even worse sleeper than his brother. The only thing that's keeping me sane is knowing that a) he'll sleep eventually and b) he's my last baby so I'll never have to do this again.
