The next time I change the naps will be if she starts to wake earlier int he morning. then I will cut her first nap to 30mins with the next nap being 2.5hrs later (I think,will have to check). That then brings teh long nap earlier again. I'll keep doing that until it's one nap. Or of course, she starts to refuse one of her naps again,and hten will need to do something different. If she starts sleeping in, then I would try one nap...doesn't happen though!
what is the routine at daycare? you know, you can always talk to them about her naps if their routine doesn't suit you. they may change...
