18 month waking hysterical and inconsolable in middle of night - anyone else?

[Whyismycatanasshat]

Can anyone offer any advice?
My DD is 18 months and has suddenly started waking up screaming and crying hysterically and is inconsolable. Last night it lasted 2 hours before she calmed and was running around her cot as if it was get up time.
I have tried cuddling her, switching the light on to break the darkness; patting her, taking her out of her room, changing her nappy, singing to distract, walking around the house, shhing and I get no where.

Last night I lay on her floor whilst she screamed for 2 hours.

She’s never been like this through the day.
She has reflux but doesn’t seem in pain- he usual reflux indicators aren’t there.

This started on Saturday; initially it was within an hour of her going to bed; she’s bumped her head earlier in the day, and had a wee egg on her forehead so I thought that was maybe hurting her but the screaming and hysterical behaviour started at 11.30pm last two nights, when she’s been in bed since 8pm; I think it was 2.30am or 3am
Before she settled and lay down asleep. She was still muttering when I crawled back to my own bed.

Anyone experienced it, any advice, thanks.

I think my DS did this at 18 months. I'm pretty sure there's a regression around then. It just got better over time.

Anytime this has happened with mine it's usually been the start of an ear infection

@passthegin1234 Thanks for replying - Just when I hoped we were regression free for a bit!

@SparkyBlue Thanks for replying; That was my first thought but she’s absolutely fine during the day and usually with ear infections we have tears and head/ear slapping and pulling, she’s prone to ear infections unfortunately due to her reflux - this hysteria is completely new with no symptoms of reflux flaring or anything. If there was anything else apparent I’d be speaking to her GP.

Google suggests she’s at the age for nightmares or night terrors. Deep joy.
