Bit of background. I have one DD age 11.
OH has one DD age 5 and we have one DS together who is 3 month old.
Basically OH's DD lives with her mam and shares a bedroom with her and gets cuddled to sleep all night (borderline child abuse in my eyes) she is almost 6! So when she comes to ours she expects the same thing. We gave her a bedroom, decorated it in unicorns at her request, all the decorations and fairy lights she wanted.... this was almost a year ago when we knew the baby would be arriving. We now have a 3 month old baby... my darling little stepdaughter still won't sleep alone. My other half is on her bedroom floor every weekend, leaving me to the night feeds while he's off work and could be giving me a break.
DS has started sleeping better and I am wanting to give him his own room and space as we now tend to wake him up coming to bed. If we don't wake him he sleeps from 7-5am (I know this from the number of times I've fell asleep on the sofa) DH won't let me give him his own room as he wants his daughter to have her own room when she sleeps. My daughter is 11 and would be happy to share with his 5 year old once a week IF she slept good .... but she doesn't!
What do I do. I'm at my wits end. I want everyone to be happy but I feel like we just argue constantly over our children!!
