Hi Enna, I split your post off into a separate topic, hope you don't mind

. Oh, the school run, I don't miss those!
Since she's waking so early, what about pushing her am nap later, say around 9:40 so she's up for 4 hrs for her first A, letting her do a long am nap and then doing a CN after the pm school run? Bt might push out a little bit though. Routine might look like this
Wu 5:40
S 9:40 to 11:20
S 3:20 to 4
Bt 7:30
Might be tight with only getting home at 3:15 and I know she was handling a long A before bt so not sure if she will fight bt. You could cap the pm nap to 30 min if that's the case.
What's the desired wu time? When she's back on track, you may have to cap the am nap and then do the CN until she can handle a long enough A for the 2:1 transition.
