I don't think many 3.5yos still have a nap. I have heard of kids that don't give it up until they start school, but George is 3 and while he still naps some days, the other children his age that we know don't. Sounds like Molly is at the point where she could give up the nap, but will continue if you decide to push it. You might like to stop the nap, make her bed time 6.30 and then move it to 7 or 7.30 when you feel she's getting through the day without becoming too tired. Or alternatively, if you enjoy having her up in the evenings, you could try to keep the nap and put her to bed at 7.30 or 8. Personally I feel I need the time out after lunch, so when George won't nap anymore I'm planning to introduce quiet room time so he will play by himself while Milly rests and I get a break.
