my dd has just been offered a place at our dream school for nursery after Xmas. Thrilled to bits but they only have afternoon slots, inevitably, as it is not popular. She will go from 12.45- 3.15. Usually she eats and sleeps at these times and that's it. Will she be exhausted? can I change her nap time or best just to cut it out altogether? don't want to miss opportunity but don't want her to be unhappy.
