What age was your baby sleeping thought the night?

I know mine was under 4 months i guess i was lucky really has they did like to sleep too the point i use to have to wake them for there feed lol.

My youngest (he is only 6 months) has been sleeping through since he was about 12 weeks!!! My eldest (now 3½) was just about the six months as I was going back to work at that point and was panicking a bit that I would be going to work sleep deprived.
