So that STTN was shortlived, as expected!!!

We didn't have a very good weekend. DD has been acting all strange and I just can't seem to read her anymore.
what do you make of our weekend routines?
Sundaywent to bed on sat night at 7:50, Had brief NW at 5:20 then slept till 7:30AM
Wake - 7:30AM
nap - 11:30 - 1:15 (she woke on her own happy. I tried to offer her a catnap around 4ish but she refused)
Bedtime - 6:30 (I tried at the earliest she was willing to go down)
NWs - 8:30 brief wake crying - was this due to OT? Strange to wake up 2hrs after bedtime. THen another brief wake at 3 and then woke at 7AM happy
MondayWake - 7AM
refused Am nap at childcare
Nap - 12:50 - 1:10 (the earliest I could bring her home and get her down was 12:45). I tried my best to AP her back to sleep but she kept crying and refused to nap any longer.
Bedtime - 6:30 as yestrday
Nws - again 8:30 then briefly cried out at 9:20.
What's happening!! How do I fix this

I really hope she naps at childcare tomorrow AM, even for a brief nap. I can't figure out whether she's OT or not. She's happy when she's awake, but whenever I try to see if she needs a catnap she starts screaming her head off so I give up.
