Oh my, we have tried everything. She was a solid 2x day 30-minute napper until December, when her AM nap suddenly went to 1hr 15-20, and then she absolutely flat-out refused a PM nap. Sooooo we tried waking her after 30 min in the AM, which led to - no - afternoon nap. So, I was happy with a long nap in the morning, because she got somewhat rested and I got stuff done, and we just worked through the afternoons (around 6 things get a bit dodgy).
So here is our "schedule":
7 wake
8 solid breakfast
10:40-11 stories and rocking for wind-down
11 nap
11:30-12:30 wake up
(she used to nurse here but has dropped this feeding - I think we're on the way to weaning)
12:30 lunch
1:00-5:30 play time, errand time
5:30 dinner
6-6:30 play time
6:30 bath
7 nurse, stories, bed
she wakes between 5 and 6 and nurses; I put her back to bed and she either sleeps or plays until wake-up time, which sometimes is at 6. There is no rhyme or reason.
I think what might have torpedoed things is that we started going to a baby story hour at the library on Thursday, which went from 9:30-10:20. It's not a long drive home, but she was falling asleep in the car, which I did not want to encourage as I can't get her out of the car seat and into the house and keep her asleep. I'm not going to story hour again until she's more into an afternoon nap. Then on top of everything, a relative here in town had an accident and required hospitalisation and a home-bound convalescence. Since I am the only relative in town and she is quite aged... well, you get the idea. LONG drives to her home. Baby napped in the car. I just ... am going to go bonkers here.
Thanks for the help and support, if nothing else. You are all wonderful.
