How old is your son? That question has to do with the naps and how many times a day he's taking them. We bed shared unintentionally with our first son until he was about 3-3 1/2 years old. It was easiest at first, gave us bonding time and we didn't see it as an issue...at first. Then like you said he has a perfectly good bed, but didn't want to use it. Honestly, we had to buckle down and stick to a strict schedule. If he cried, he cried, but we didn't go get him. We had to make sure he went down at the same time every night, the same way until a routine was established. Now he sleeps through the night every night in his bed. You have time and the power to adjust his schedule. Sit down figure out how much he actually sleeps a day, if too many naps or too long of naps cuts into when he actually sleeps and when you want him to sleep cut them out. Both of our boys required 10+ hours of sleep between nap and bedtime; we adjusted the nap length and the sleep worked itself out. But like I said we had to be strict about where he slept and we used rewards for both of them based on how many days in a row they could sleep in their beds. Hope this helps!
