Ebadge-
For our oldest most of our co-sleeping was a nap time. If he awoke during the night once I went back to work, I just bought him in bed with us. which seemed to be about once a week at that time. Then around the time we were adopting our youngest, our oldest became more clingy especially during travel, so he slept alot with us. Once his brother was home, he seemed to sleep half the week with us and half in his bed. not a great habit to get into, because bedtimes then became a hassle. by this point he was home 3 1/2 years, So we got firm in terms of how many times he could get out of bed for questions. I gave him 3 tickets to get out. That worked. now they only sleep with us if someone is sick or scared, we don't send them back to their beds if they get up in the middle of the night. mainly I am too tired to deal with it and it is easier to just let them in. But that doesn't happen too often.
I think the longer it goes on the harder to break. my friends' 8 yr old (bio) still wants to sleep with them, so someone has to lie down with her to go to sleep.
we just did whatever worked for the kids and us.
