I wouldn't worry. My DD was sleeping 13-14 hours straight from 5 days old through the night with the day sleeps ontop. My family health clinic nurse told me I should be waking her for feeds etc through the night. Mum (who was staying with me for the first couple of months after DD was born) told me to let her go, if she gets hungry she'll wake. I took my mums advice, afterall she has raised 4 kids herself, & I'm so glad I did. I stopped feeling guilty for letting DD go so long between feeds at night & I've never looked back.

You obviously have a very happy & content little bubba who likes to sleep!!

Enjoy it... it could change anytime!
