Yes...as Rachael said it is quite likely the child was exhausted those first few days and passed out quickly...also I find some kids put up less fight with naps at first because they are not yet comfortable in the new environment. The difficult nappers soon get comfy and their usual nap habits start to show.

I find it odd to terminate a 15month old because they don't eat soups and stews, they learn to eat it soon enough - or go home hungry. I suspect the provider may have not given all info because they wanted the child to find new care.

All you can do is be clear with home about the struggle (both how it impacts you and how it impacts their child). If the child was kicked out of their last daycare because of poor nap habits then they really should have been honest about it and found a daycare that can accommodate the habits they have engrained in their child or they needed to be ready to make changes at home so their child isn't bounced around from daycare to daycare.

This always baffles me about parents! I can totally understand how the bad habits come into play...but if they know their child is going to be in daycare and they know that child will not be able to be held for every nap then they do their child no service what so ever by not preparing them for sleeping at daycare. It can be done gently and lovingly...BUT it has to start when the child really, really young. Gahhhhhhh

Best of luck! How long was he at the other daycare? since 12months? I personally would almost be tempted to call the other caregiver back. Nicely and saying look, this child is really struggling with naps. I suspect you had the same problem...can you explain your nap routine and what strategies you tried there so I don't waste my time here starting from scratch. Then you'll know where to start (hopefully)!!
