Thanks

Brace yourself, this may be long.
So her day now looks like:
Wake 5-6am
I hold off her feed as long as I can by trying to keep her in cot
BF 6ish
Sit in quiet room until 6:45
Breakfast 7:30
Snack 9:30/10
Lunch 11:30
Nap 12-1:30ish
Snack 2:30/3
More snacks
Dinner 5/5:30
Bath
BF 6:45
Bed 7
So as you can see there's an ew there.
Prior to this, our routine was:
W 6:30/6:45
BF 7
Breakfast 8
Snack 10
Nap (had to push her to have it as she wasn't keen) 10:15-11
Lunch 12
Nap in car on way to school 2:30 (had to drive around for ages to get her to fall asleep)
Snack 3-4
Dinner 5ish
BF 6:45
Bed 7
She got sick and got very sleepy not long after wed moved to one nap. So she had heaps of daytime sleep, and since then the ew has gotten worse and worse. She doesn't take milk in any form other than me. I'm exhausted and over it. I'm trying to keep her quiet each morning so my boys don't wake too early for school.
I'm open to your suggestions. I feel limited by school pickup and after school activities which mean that she can't sleep/won't sleep when the other kids are in the car. So if I do second nap, it has to be before 3pm. Dh isn't much help- mainly because she screams when he's there at the ew and so to keep her quiet I just go in. In the last three days, she's laid back down for about 15 mins while I'm patting her. But not slept unless she's fallen asleep during the BF, which she did this morning.
Sorry for blathering on! Thanks for your help xx
