10 week old sleeping 12hrs a night?

[MrsMotherHen]

The last two nights my 10 week old has been sleeping from 6.30ish until 5.30/6.30 I know how lucky i am my first didnt sleep through until he was 18 months!
We normally dream feed her at around 10pm of 4oz but last two nights she wont even entertain them and wont take any I thought she would just take more in the day. She only has at most 20oz a day its normally about 18oz she had anywhere from 2oz to 5oz per feed.

Am just worried she wont put on weight now shes not feeding in the night. She was 7.2lb born and last tume we got her weighed she was just over 10lb a week ago.

what a cute baby

My third born slept 12h uninterupted from 7 weeks old. In fact from the very night he was born he never had more than 1 night feed in 12 hours in any night. He was a 50th centile baby and maintained well.

DC1, DC3 and DC4 all very different.

My nephew was like this, always just slept loads. 12/13 hours a night plus a 3hour nap in the day as well until he was nearly 3. My DSis actually took him to the doctor once because she was worried how much he slept!
As long as she's eating enough when she's awake don't worry, she'll wake if she's hungry.

My son did this for three weeks from about 12 weeks old but 4 month sleep regression hit and we're only just getting back to 10-12 hour nights at 10 months old. He kept putting on weight during those three weeks.
