Toddler hysterical screaming same time every night

[RegalRags]

My 16m is waking up at around the same time every night screaming hysterically. She is completely inconsolable and will scream till she vomits.
This was happening occasionally from around 3 months of age and is now every night.
She has a good routine, bath, book and bed around 7:30.
Down to one nap a day around lunchtime and eats well so is t hungry.
She is teething but has pain relief so I doubt she's in any pain.
Once she's stopped crying she is wide awake till the early hours.
It's almost as if she is having night terrors but is wide awake.
Any ideas? I'm absolutely exhausted

It does sound like night terrors.

If it's at more or less the same time every night you could try going in and waking her slightly before the screaming starts, in order to reset/change her sleep cycle.

I'd also try and film her, either get a baby monitor that films or set up a phone/camera to see what happens immediately before she starts screaming. Maybe you can get a clue from that.

I tried going in to her tonight and she was worse than ever.
I did think night terrors but because it started so early maybe it is something else?
The camera is a good idea, will get that set up ASAP.

What do you do from the moment she starts crying until she's asleep?

What time is this wake up?

Finally, how do you get her to sleep at bedtime and naptime?

Agree with nightterrors. All mine suffered we found a variety of things helped,
Going in the room just before they woke and tucking them in turning them slightly not enough to wake them but it seemed to break the pattern. If a terror was in motion then trying to calm them down made them worse so I just used to talk quietly about bizzare things, just general conversation and often they would just suddenly calm down and go back to bed. Seemed to work best if the things I talked about were random and about something they cared about so might say doggy went swimming today in the swimming pool, he took his swimming hat and pool float and even wore swimmers. He's very good at diving etc this seemed to get through to them when calming them didint.

It does sound a bit like night terrors, and a big culprit can be screen time - I know my son has weird wakings (still asleep but eyes open and crying) when he's had too much screen time and is a bit over tired.

If it's the same time every night, could you try going in ten minutes before then and rearranging her blanket or duvet? The idea is it is 'rouse to sleep', it's gentle enough not to fully wake them, but rouses them slightly enough to ease them into another sleep cycle. It sounds risky but it does work in my experience!
