Hi hunny! Let me just offer up my support for you during this difficult time and say how much respect I have for your hubby and you!
First of all, lets put this whole infant/young child thing in perspective. Babies are babies for only a very short time, and I personally believe that co sleeping is a big positive in their life. It allows you to nurse without losing any sleep, and it really strengthens the bond. They really don't stay in your bed forever, I promise! When he is getting to the point where he isn't nursing so much through the night, that is when to start transitioning him into his own "big boy bed" It really doesn't take too long once you've established a routine, kids definitely adjust very quickly.
Secondly, I totally agree with you about the fact that parents need their own bonding time. But you have to realize that intimacy happens on many different levels in a marriage, not just a physical level. That being said, it can take place in any where, at any time. As far as the physical stuff....it certainly doesn't need to be confined to a bed, or confined to night time hours for that matter! Be creative in your quest for "bonding" with your hubby, and your marriage will be stronger for it.
Good luck to you!
