my 1st didnt sleep all night till I had my 2nd child he was 4 and a half!!
2nd used to get up once hav feed and straight back to sleep
but my wee girl has amazed me she goes down from 8.30-9.30pm and she will sleep right through till 9-10am

!!!!! shes been like that from about 2 weeks old

but shes never really slept thru the day maybe an hour after lunch if Im lucky but who cares if she is sleeping all night I say
having a girl has been far easier and a lot more relaxed or it could just be me older and less crabby??

lol
