Is there a 3 year sleep regression!?

[SquedgieBeckenheim]

DD1 is just 3 years old. As a baby she was a crap sleeper, then we finally cracked it just before her 2nd birthday. Few months later ditched the dummy and all was fine. Till about a week ago. Now she is terrible at going to far-reaching screams the house down, and wakes randomly in the night screaming. She won't tell us what's wrong, why she's woken up. She's normally a daddy's girl, but won't settle with him at night any more. I have to sit holding her till she stops screaming then she'll get back into bed, and I have to sit next to her till she falls asleep. If I dare move she'll start again.
I don't mind doing this, but between that, feeding dd2 EVERY 3 hours and General rubbish sleeping due to anxiety I am getting next to no sleep!
So, is this a thing? Will it pass on its own or do I need to do something? We've tried finding out what is waking her, but she just sits there in silence or screams!

Could she be having night terrors, our 3 year old has them sometimes. www.nhs.uk/Conditions/night-terrors/Pages/Introduction.aspx
That is a link that explains them.

Thanks for your reply.
It could be that I suppose, but she does seem to wake up at least by the end of the screaming episode! It also doesn't explain the screaming when we try to put her to bed. She has a good bedtime routine that has been in place since she was 6 weeks old - bath (Or shower now if she wants) stories and into bed.

We've been having bedtime battles with really silly behaviour before bed and so have a few of my friends with 3 year olds. Is she upset or just making lots of noise?

In our case there definitely was a rough patch at 3. It didn't last long though, maybe 2 weeks.

She's upset. Silliness we could, and do, deal with. But we get through the bedtime routine and when we try to leave the screaming starts. If we try to leave her to it she gets worse. It's not every night, but getting more frequent.

It sounds like you have a new baby in the house. Could this be your DD's way of dealing with that enormous disruption to her life? I know it doesn't help but it certainly could be related.

We also have a baby and so maybe they are doing the same thing. But our DD it is silly behaviour and yours is being upset? I hope it gets better soon.

DD here is 3.1 and her sleep is going through a bad patch too. Much harder to get her to bed and waking in the night and coming in to us. Really hoping it's only temporary as I think we're close to a vicious cycle of me tired and stressed -> her sleeping badly -> me more tired and stressed etc!

The new baby is 3 months old, and the sleep problems are only for the last week and a half. DD1's sleep wasn't even disturbed the 2 weeks we were in hospital with DD2 when she was 2 months old. If it was reaction to baby wouldn't it have happened sooner or when things were more unsettled?

My children were around 3 years old when being scared of the dark began.

We out dimmer switched and low watt bulbs in their overhead lights, then kept the light on but dimmed down all night in bedrooms.

She has a dimmable bedside light, makes us turn it off!
