2.5 year old suddenly waking at 1.30am every night

[Windywenceslas]

DD1 has always been a brilliant sleeper, until 3 months ago. She suddenly from nowhere decided she needed one of us to sit with her until she is asleep and wakes at 1.30am, like clockwork, every night and comes into our room. The only way to settle her back in her own bed is to let her come into our bed for a cuddle for at least 15 mins. She often then comes in again between 3 and 4am.Then she's up again between 5 and 6.30 to start the day. I'm exhausted. I have a 6 month old, who thankfully sleeps through most of the time, but when she's having a bad night we get no sleep at all. DH travels a lot for work, when he's home he's a big help, but a lot of the time I'm on my own.

Any tips, this is genuinely new territory, both when babies slept from 8pm-9am regularly from a few weeks old and self settled without dummies.

If we try to take her straight back to own bed, or don't stay until she's fully asleep all hell breaks loose and baby gets woken up, then I'm not allowed to go downstairs to fetch a bottle for baby without the tantrum to end all tantrums starting up.

My son is the same always been a great sleeper from 13 mnth and now he is 3 and form past 3 weeks he refuses to go to bed unless you stay with him and stroke hos head till he falls asleep and then I have to sneak out the room once asleep. But then he wakes up around 1.30 am every morning and refuses to go back to sleep he won't stay in his bed unless your in his bed with him, he won't go in my bed. He just wants to get up and stay awake he usually falls back to sleep around 5/5.30 am. I am literally shattered am so tired as some days I only get about 3/4 hours if im lucky. I walk round like a zombie most days and my son usually us very grumpy and has alot of tantrums in the day because he is also tired. Which is very challenging when you have had no sleep. I have tried everything I have ever read everything I have learnt from looking after other kids bit nothing works. Anyone have any ideas please let me know
