Kiddo won’t sleep!

Almost 19 mo old kiddo has never been a great sleeper, but for a few months we had a good routine going! She had a consistent 7pm-7am night sleep with 1 daily nap around noon for exactly 1.5hr. we still rock her to bed, but usually only took about 15 min and then we could lay her down. During thanksgiving week her schedule obviously was thrown out the window. We tried resuming her normal schedule Sunday night, but now she just screams the second we lay her down for bed. Shes waking up multiple times a night and will not go back to bed without hours of rocking. Wtf is going on?! Is it just due to the holidays?! Anyone else having sleep issues right now??? I’m in my 3rd trimester with our second kiddo and I’m exhausted and sleep deprived 😭😭 any suggestions??
