Sleeping to much!!

[Lannybannany]

My baby is 12weeks today and has always slept well for 5 weeks from 12 until 6am. Now she sleeps from 12pm until 11am! Without waking has 5oz and goes back to sleep. Is this normal...is it safe.. ?

How is weight and nappy output?

That's 23 hours, that's not normal I would get baby checked asap.

Do you mean midnight until 11am or 12noon until 11am?

My DD was always a big sleeper, but it started when she was about 2yrs old.

Do you mean 12am - 11pm? If not, definitely get your little one checked out. 23 hours of sleep is really worrying.
