Definately follow your gut feeling, not theirs. However, If you know that you are a person who is resistant to change yourself you may want to reevaluate a little to be sure that it's her that you feel is not ready, instead of you.(just a thought, as I know some friends that are more hesistant to transition when the kids are fine with it) My daycare usually spends a few months "in transition" where the little kiddies will spend just the morning in the toddler room and then it's back to the comfort of their crib for naptime and the afternoon. It's all in how much you trust your daycare, if you're kinda knew there maybe you haven't had time to really know how they are and gain that sort of "you know how to do this" trust. I remember feeling reluctant myself (with just a hint of excitement) about the toddler room, and I would chuckle "you think you're going to get him to sleep on a cot, gooooood luck with that" but they did, day one!! yahoooo it made the transition at home that much easier!! So, at 15 months out of nowhere --- Perfect, I"m going to like this I thought. And though he was still on two naps most days - nap times at home were getting pretty eratic, yes two of them but I never knew when or how long, so the switch to one nap was not so horrible, he adjusted really well, and finally slept the same time EVERY day, with an even easier early bedtime. Things were much easier to plan around because thanks to daycare routine, he had a routine to follow day in and day out I stuck to it at home whenever possible. Good Luck with what you decide. Oooh ya,, i also remember sippy cup craziness, i went thru soo many brands til i found one he would use, it had a really soft top "like" a bottle then I gradually went from one cup to another as he got use to it. I took all his bottles away on his 12 mos. birthday, he didn't care once I found the sippy cup he liked.
