Most babies I have heard of, either sleep through constantly (once they figure it out) or have never slept through.

Cooper first slept through 6.30 pm to 6.00 am at 9 weeks old. Ever since then he has done it for a week or two at a time and then he'll change and perhaps wake around 3.00 am for a few days or a week. Then he'll sleep through again for a week or so (maybe to 5.00 am).

Every time he does it for quite a while, I think, "This is it – he's finally going to sleep through all the time". But he never does!

I just find it strange!!! He's keeping me on my toes!!!
