Hi Ima shel Anon,
It's been a while since I posted here. My daughter is almost 7 months old in a little more than a week. And for the last month I've been trying to determine what A time is best for her. And I had a success only one time when her nap was 1.15 min. At that time her A time was 2.30. And after she made that nap I considered it UT and decided to go up to 2.40. I'd better left it 2.30. Because the routine went all over the place. It was very difficult to keep her up 2.40, because sometimes she would wake up at 5 am and practice her rolling skills for an hour and then she'd go to sleep but for 40 min. So she wakes up at 6.40-7 and it seems like she cannot handle full 2.40 A time because she had that "pre -wake up" activity and then slept just a little bit. So I'd cut her A time. I don't know, maybe I should still keep her 2.40.
After all these efforts I could hold 2.40 for some days, but naps length were so different, I don't know in what direction should I move now.
For first 2 days she had A time 2.45 and had 45 min naps. On third day she 2.36 A time, but woke-up after 26 min. Then 3 days in a row she had 2.40, 2.42 and 2.43 A time, but naps were 50 min, 16 min and 30 min. So, i'm trying to understand If I should go up or go back to 2.30. What is your opinion?
I'm tired to stay on this particular A time, because I don't see anything good comes out of it and tomorrow I'm planning to go up to 2.50. Do you think this is the right idea?
