Please be gentle with me, first post posting in absolute desperation 😭
My DD6 wakes up every night and has a tantrum for 2-3 hours. We have another DC whose 18 months and I'm due our newborn in the next couple of weeks.
The tantrums range from; I've got tummy ache, my legs hurt, I'm tired, I'm hot. We will keep taking her back to her bed and she will follow us back, as mentioned this lasts for 2-3 hours. If we stay with her in her room until she goes to sleep this will again take 2-3 hour of us sat there/laid there as if she's not tantrumming she'll just toss and turn. DH has severe back pain from doing this most nights. The peak of the tantrum is always that she wants to come into our bed, she has never slept in our bed and we can't start this now with a newborn incoming.
Spoke to school, no underlying issues there at all.
We are exhausted. She is usually more reasonable for DH than me, he's up super early for work in a morning. This has gone on for 5 months. Tried reward charts, taking things away and makes zero difference as she isn't bothered. Gets more than enough attention from us in the day.
Any tips on how to sleep train the most stubborn 6 year old in the world before we both keel over from sleep deprivation? 🙏
