I think you both need to relax.
Listen, even if your baby slept in your BED until he is three, he's not going to turn 19 thinking the ONLY place he can sleep is in your room.
There is no "should" or "right" in this regard. You have to judge the actual needs and appropriate actions for you're individual children based on individual merits.
Both, you and your husband are parents. His feelings, instincts, intuitions are just as keen and important as yours--it's so silly how women (not saying your are) deminish that and dismiss a father. Anyway, if he's not comfortable, perhaps he's tuning into something... Your son is very blessed to have such a concerned and committed daddy!
Babies move around, that's a fact of life. There is nothing you can do to prevent it. And, as harsh as this may sound, if something is meant to happen to your little guy, it will one way or another. So, your instinct to trust things will be ok, is also very beneficial to you and your son. Your little guy is blessed to have an insightful mommy. You can't protect him from everything and allowing him to live in experience is a good way to go.
Whether you choose to bag the crib and just put him in bed with you, you leave him in the port. crib, you bring the big crib into your room, you camp out in baby's room while he sleeps in his big crib down the hall, or you decide to hang from the ceilings...it's all fine.
You know, we've held close to the principle of if one parent says NO, the answer is NO...even if the YES person thinks the NO is utterly ridiculous and STUPID! (oh, and THAT has happened several time on both sides)
Just tune into your own rhythm as a couple, as parents, and make the best decision, the second best decision, the third best decision and work your way up the latter. And realized your top three may not be what your Mom, the Dr, the neighbor, your Father-in-law, the store keeper, or the bus driver may agree with, BUT this is YOUR baby, you're family, and YOU and your husband (PLEASE don't forget your husband)are the two people in this planet who get to receive full access to inspiration because your son is under YOUR stewardship, not ours.
It'll all be ok, you'll see.
