Yes, there are consequences to letting your children sleep with you. Consequences like having a SECURE, INDEPENDENT, LOVING, CONFIDENT child who knows his parents are his safety and he can trust them.
Yeah, I was being a little smart-alecky there but it's not aimed at you. I just get frustrated often by the negativety that surrounds cosleeping. It's totally unfounded. There are entire nations where cosleeping is the norm. It's really only here in the U.S. and some European cultures where cosleeping has the stigma of (1) being unsafe and (2) spoiling children (3) creating clingy, dependent children.
I can tell you that our toddler slept in our bed until almost age 2 and now sleeps just fine in his bed or in our bed. He can do either easily. Sometimes he wants to be in his bed and sometimes he wants to be in ours. Sometimes he goes to sleep in his own room and comes to our during the night.
I think it says a lot about your husband that he enjoys the family bed. It says he is a loving and nurturing dad, it says he is confident in his parenting to not let 'society' dictate his parenting choices. This 'instinct' will carry him thru many more parenting delimas.
With this being said, there will come a time when the parents or the child is ready for the transition. I suggest taking it slowly. You can start with his own mattress on the floor of your room. We used the side car arrangement for a long time. It's where the crib attaches to the bed so you actually get the best of both worlds. Baby has access to the bed and likewise. Here's a link on how to set that up http://groups.msn.com/SteveandLishsFamily/sidecarcrib.msnw
And here are some great articles on cosleeping:

It's obvious I support cosleeping so I want to encourage you to continue as long as YOU and HUBBY feel ready, not just until you feel pressured to quit. Trust me, there are many, many families that do it, they just stay quiet about it for fear of being labeled. And for the moms who will tell you that you will one day regret it, your child will run the house, your child will be dependent, clingy, etc. I say HOGWASH! Children can be simply born that way or made that way by other parenting techniques. What did our population do before the invention of cribs or multi-bedroom homes???
Oh, yeah, one more thing. I know it's going to be mentioned here.....SEX does not have to happen in the bedroom only. As a matter of fact, the more you take it out of the bedroom, or bed for that matter, the better it gets!!! Sex doesn't have to just be at bedtime either! When we actually wanted our bed, we could put baby down on a floor pallet or in his crib (which was really just his toy-holder!).
