Let him sleep in your bed. It's as harmless as letting your baby wear diapers. One day, he will use the potty. And one day he will sleep in his own bed, without any tears. You and your husband can enjoy the bond and intimacy that comes with a family bed. You won't feel any guilt and your baby will feel, "Yes, my mommy is my parent at night and during the day", "I'm safe". Try it....There's great bed rail out there, so that you and your husband can lay next to each other. And as far as intimacy between you and your husband is concerned, be creative....You can even buy a twin sized bed and put it in the baby's room, then just sneak in for a little time alone. Or there's the kitchen, or the dining room. Just have fun with it!!! Research this carefuly before you make a decision.
I went to my parents room every night until 10 or 11 years old. They always made me go back to my own, then I would cry etc... I wish they had let me sleep in there as a baby and toddler. I might have been more secure and I wouldn't have all of these bad memories of childhood. Why didn't they want me in there? They would have gotten more sleep and so would I.
You could use the closeness at night if you're planning on going back to work. Check out the book "The Family Bed".
Good luck!
