The medical definition ladies of sleeping throught the night is 5hrs! So all those studies you see where they say a certain % of babies sleep through the night by such and such an age means that they are sleeping longer than 5hrs - so those of us with babies who sleep better than that count our lucky stars!!!
I knew I had read this somewhere before! I was trying to tell my mum about it.

How ridiculous. In that case, Cooper has been "sleeping through" from 2 weeks old.

Because of the time Cooper has his last feed, sleeping through to me is going 12 hours between feeds (not having to get up through the night). Currently he goes 8-10.

Although last night he slept through for the second time. He went 11 hours between feeds - from 7pm to 6am. Yay!
