So glad you have decided to to go with CC right now, as you didn't seem very keen.
I did CC with my dd1 at 9months and though it did work, I think it has been somewhat detrimental to her wellbeing. She's now 7 (yrs) and still finds it very hard to go to sleep by herself.
I was just like you, under some pressure from DH for things to be 'normal' ie everyone sleeping in their own beds all night.
If I could go back and have that time again, I would do exactly what you are doing now and try to make sure my dh was not feeling neglected.
I do think if I had just taken dd and slept with her in the spare room instead of contstantly fighting with her to sleep on her own, she would be alot more confident and a less anxious child now.
Remind your DH that this time will pass. Whenever you decide to stop BF (I stopped at 12mo) it's likely there will be a big change in her waking habits anyway. She may well sleep through the night of her own accord when there is no milk to wake up for.
Try PUPD, try not feeding her at night, just trying to settle her, you could try offering water in the night?
Good luck, I know it's hard when you are torn between dd and dh, but try to stick to what your insticts are telling you.
If your dh is very keen on CC - I'm sure there are articles online which suggest it's not necessarily a good thing for children in the long run, sounds like he is a very caring dad.
