Can she get by on one nap? If so, I'd try something like this:
6 - awake (maybe play in cot for a bit?)
milk, breakfast, milk, lunch
12:30 - nap til 2:30
milk, dinner, BT milk
7 - in bed asleep
Otherwise you could do what we're doing at the moment:
6 - awake
milk, breakfast
10/10:30 - nap for 1.5hr
milk, lunch
3:30 - nap for 30min (this may not be enough A time to BT but it would probably be ok given its not a restorative nap)
milk, dinner, BT milk
7 - in bed asleep
To get that longer nap in the morning, the first A time has to be active and I mean really active, but then your daughter may be different from DS.
Hugs! Its not easy figuring out these tiny humans, is it?
