If my last week is an indication- take em on a trip for a week to visit fam that's not close by, they'll not sleep a wink and fight every nap, then as soon as you get home they'll sleep like the dead for all naps and bed times lol Honestly, no idea though. Best of luck?
My oldest turned 2 a couple weeks ago and she’s the same. She’s also been waking earlier then normal.
Same with us! My boy has been going through a regression, up super early and calling out randomly all through the night. We're shortening his nap to see if it helps, but so far not much luck.
