Sharing sounds like a great compromise!

I also wanted to say that you and dh need to be united on your approach to prenting his dd...it sounds like you feel she is getting between you and you sound upset by that. Why can't you and dh have an agreed bedtime and ritual? If she needs him in the night- fine he can go to her, but at least you start the night with her in her own bed and you and dh with some time together. Six is very young still, and she will be dependent on daddy...but it's ok to have some basic rules around bed such as the time she goes to sleep and who comforts her etc.

Forcing independence is forced detatchment. Children need to feel safe and secure to thrive.

Good luck!
