When does a baby sleep all night?

Helen

At the moment I put my 7.4 week old baby down at 1am and she sleeps most nights till 6. I think I’m quite lucky for this. But now often I’m not going to bed till 3am because I’m enjoying a bit of alone time from all the family.

So when can I put her down say 7 8 or 9 pm and enjoy some alone times till morning time?
