DD1 id 2yrs 7months. She has been having 1 nap a day of approx 2hrs for a while. Recently we are really struggling with it; often she will play in her room for ages rather than napping and then either fall asleep too late, like at 3pm, or not nap at all. She seems tired at around 1 so I think she still needs it but I can't force her! She wakes up at 7am, would normally nap from around 1-3pm, then sleep at about 8pm. When she skips her nap I go for a 7pm bedtime. What should I do? Should I keep persevering or accept that naps are more or less over?
