J as sleeping through the night from 6 weeks until it went pair shaped at 7 months. At 12 months he would have been waking a few times in the night. And sometimes just once - but not going back to sleep.

T was a shocking sleeper day and night for about 4 months, then was waking once or twice overnight until a couple of weeks after turning 1. Now he sleeps through nearly every night, if he does wake he usually just wants a cup of water (and this is pretty rare).

So for my boys they were two extremes, no real average at all. And interestingly that the one that started off as a great sleeper is now not so great, and the one that started off as a shocking sleeper has become a great sleeper! Maybe that will happen for you!
