Hi there,
Could you do something in the middle? Lets say she goes for her first nap at 10, so go 9:30 in EW days?
You can go both ways here, but from my experience guiding A time more than the time of the nap made my DS get use to EW, so we were changing that for 3 weeks:/ I would personaly do middle solution. Gradually extend A time to shift her back to normal.
Do you know why she EW? Do you wanna write down your day for me to look at?
