Napping

Socially at daycare Camryn is doing great! She hasn't really cried and she's getting along with everyone. She's eating all her food and doing really well. The only thing she's struggled with the last two days is napping. Camryn is only used to napping in a pack n play or in her crib. This is something completely knew to her. She now has to nap on a mat with a sheet and blanket. Something she has never done before. Don't get me wrong Camryn has NEVER been a good napper but she usually at least gets 45 minutes in. (She had trouble napping when she had her cast on too and was stuck in the red wagon) Yesterday and today she got only 20-30 minutes each. So now, as I sit here on my couch she is a hot mess and super tired because she didn't nap long enough today. If I put her to bed too early she'll wake up too early so I'm stuck dealing with a mess of a child until it's bath and bed time. Did this happen to anyone else? Do they ever get used to napping not in their crib?
