Hi!
Typically EWs at this age indicate too much day sleep. Is that what we determined before? Can you post her latest routine?
Not sure in your case, but my son cries upon waking when he wants to sleep but can't for whatever reason, so OT. Catch 22 with the short overnight sleep, and long nap. They're so tired they don't want to wake from nap, but unless something changes consistently, it'll be a cycle.
Turning 2 is a big birthday! There's certainly the developmental factor here. I think separation anxiety kicks in again for a little while.
I know you don't want to reinforce the early wakings by going in so quickly, but if she's screaming, something is off and she needs you. I always go in and very quietly, sometimes without a word, just give him a quick back rub, and sometimes fall asleep on the floor next to him if needed to keep him in bed. (We kept pillows and a blanket near his bed for this!) Then we make a huge deal when our wake up light (green) goes off. And slowly, give or take a few days we'll say, "ok, mommy will stay a little bit and then leave the door open for you." And make sure she says OK and if she screams again, come back. Give her a squeeze and kiss, then say I'll come right back if you need me, and leave again. You can adapt this to however you want but keep the mentality that whatever you do is to help support her. Honestly, for us, it lasts a couple days and then he's back to normal.
If she wants to be held, hold her, then gently hold her down onto her bed and snuggle with her.
More than likely it's a phase but I think we want to reassure Lo's that we'll be here and help them transition to more independence again. And wrt to the early wakings, we'll see what's going on with her routine. Thanks!
