Any long term co-sleeping parents out there?...?

We starting co-sleeping with our son at birth. I never thought it would last as long as it has but I don't regret it at all. Since November he has slept more in his own bed, or at least we have taken him to his bed after he falls asleep in our bed. We have tried to put him in his own bed to fall asleep, but one if us usually ends up 'sleeping' in there with him until he falls asleep. He will be 3 in July, my daughter is due at the end of June and we don't plan on even putting her in our bed. I don't want it to be too crowded in there :)
