You know....
As someone with lots of experience with kids and babies, some just cry before going to sleep.
It's like their last little struggle, their last little fight, their last little burst of energy before they konk out.
I have literally known kids that don't go to sleep without crying first whether they are being held, rocked, nursed, driven around in the car......they just cry before sleep. I don't think it really hurts them. They just have to decompress before they can release the events of the day and knock themselves out.
Lots of kids just let it all out and then they're gone to slumberland.
It's hard to listen to them cry, but that's what some of them do.
It's okay.
Many kids fight sleep because they're afraid something really exciting will happen and they'll miss it.
I have known many sleep fighters in my day and you just get used to it. You can't cave all the time because that will just extend it. All kids need naps and regular sleep schedules. They don't always like it or understand it, and sometimes crying is just part of it. It's not easy to listen to, but it's not the end of the world, either.
Just reassure her, know that crying is okay, and things will work out.
Just my opinion.
