Becky, thanks for all your help first of all!
I've shorten A time and we're doing somewhere about 5.15 hrs - 5.40 hrs - she's in bed usually at 5 hrs after waking up (+ - few mins).
She's been napping better - sometimes it was as long as 2 hrs! But usually it's between 1.20-1.45 hrs.
There was one day, she couldn't fall asleep even when I was with her - she didn't nap that day. She was laying there for 2 hrs talking.
And she has started waking up at night few times, but I know her molars are coming out and probably that's the problem.
The other new thing is, that we had few days with EW's. She was usually up at 7.30 - 8.00 am, and last week we had 3 days when she was up as early as 5.15 am! Today we had 6.45 waking up, but yesterday she was sleeping till 7.45 am.
She's in bed in the evening after 5 hrs of A time, asleep usually within few minutes.
Should I do something with it? Like lenghten her A time before bed? Or maybe shorten it?
