asleep for 7.10.in bed for 6.50 but sang for a while b4 falling asleep.
So bang-on 10.5h nightsleep...I have always had a hard time with this one, the 10.5 as I've never known if it is UT or OT. With D I think I would normally assume it was just all that she needed but if she had only 30 minutes nap and so late in the day then I just can't see how it could be anything other than OT.....and that again teeth played a factor? That if she wasn't teething, she may have rolled over and gone back to sleep perhaps? Hard to say, really.
I realise it's 1200 now so you've made a nap decison, but I would be inclined to try to hold her off until 1130,based on what happened yesterday, give something for teeth and see if it's any better than yesterday's nap.
Let us know how the afternoon goes xxxx
