UNC mom, I was putting her down to sleep after one hour, but then I started to think that she wasn't really tired enough and it was causing fussiness going down and short naps. Now I put her in the crib at about the hour and a quarter time and then she is usually asleep by th 20-25 past. Sometimes if she is too tired she has to have a mantra cry which lasts exactly 7 mins (too funny). It took a lot of tinkering to find the right activity time limit. My Lo is spirited/touchy and she is not good if you miss her window. Even worse if you miss a whole nap....we pay the rest of the day. You probably want to tinker with her time a little and maybe you can get her going to sleep a little faster. If she doesn't fuss for that 20 mins trying to go to sleep than you might be right, butif she fusses for 20 mins she may need more awake time. I wouldn't go less than an hour at her age. Someone else on here told me that at this age they needed about 1.25 hr awake. It worked like a charm and some naps now she doesn't even get too mad at the 45 minute marker. Alos, sometimes my LO's sleep que is the first little whine. With a two year old, I can't sit around watching for every yawn, but if I move quickly after a little wimper, I can catch it in time. Hope this helps!
