I don’t have any advice but I can relate in a way. My son will be doing his own thing and chillin and out of no where even when nothing has pissed him off he will just start screaming and crying and be so angry to the point that I can’t even console him. And the. Started telling us during these episodes that he doesn’t like me or his dad. To us it seems like PTSD but to anyone else they think it’s a tantrum
I wish you the best of luck love and I’m always here if you want to talk.
My son is doing the same right now. Cries at drop off and doesn't want to let go of me, but then doesn't want to leave when I pick him up. I would say they're having a hard time with transitions? Talk to their teachers and see if you can collaborate on a plan to give your kiddo a 5 min (or maybe less) warning on when playtime is ending or any time they are about to do something different. Have you noticed similar behaviors at home? Like when switching from play time to meal time?
By the way when she gets inside she’s fine.
