Well dh and I have coslept with each other for ten years and it hasn't impacted our independence. As BG has said, the babe in the bed only adds to the love we feel for each other. It also forces some sexual creativity

I recommend you try it with a newborn babe some time. It feels soooo good!! And helps with milk supply, night feeds and generally fosters a well adjusted little human.

All mammals sleep with their young. I am not sure babies are the ones who benefit from the physical distance (western, modern) humans often impose on their children. But each to their own.
