As a child I had "quiet time" until I started school at 5......so even if Molly doesn't "need" the sleep, it gives you all a chance to refresh, IYKWIM?

I would watch her cues and see how you go.......

I have a champion sleeper in Olivia (who is 2 and a half) and I reckon she will be napping until she starts school.....hope so anyway.....when she naps, it is my golden time!!
