DD2 was 4 months on Thursday. Since then (how did she know? ) she has started waking in the night and being awake for up to 2 hours at a time.This goes on all night.I think we had about 3.5hrs sleep on Thursday and about an hour more on Fri. She previously used to wake once, feed (BF) and go back to sleep.
When she is awake she's hyper, pumping her legs continually and shouting out. She does feed but isn't really that interested. She sleeps in a crib in our room in gro-bag and we have blackout curtains.
Does this sound like sleep regression? How long is it likely to last and is there anything I can do to help?
Thanks
