Yesterday we moved into a new apartment and now DD has decided not to sleep. She's taking over an hour to be put down and wakes frequently (falls asleep, wakes up and cries, 1 minute later falls asleep, repeat...). She has been stayin with MIL during the day and she hasn't been napping great. She doesn't really follow the schedule I give her so I know DD is overtired when we've picked her up.

Is it because its someplace new? Is she scared? Or is it because her schedule is off? I don't know what to do! Let her sleep with us? CIO? I've tried just going in and patting her back etc and it doesn't work.
