No wearable blankets at daycare

Omg what is my baby going to do? Never nap? I just found out the daycare* (who seemed to blame the state (VA)) does not allow ANY blankets even wearable ones, no swaddles, nothing in crib. How will my LO get any sleep? Has anyone else encountered this? Any tips? We have a month to try to get used to this but my baby is a wiggle monster. There's only 2 for 8 infants so holding her for her 6 1 hour naps is impossible. She is going to be so miserable. If she doesn't nap it's not like she will just nap when we get home.

ETA: she will be 4.5 months next month when she starts daycare

ETA: I'm more worried about her being able to get to sleep and stay asleep. I think its more of a sleep cue and restricting her movement problem. I'm not sure how much warmth she needs, if thats the problem. What do you usually dress them in for sleep, if not using a sack? Is it different from play as a cue?
