We co slept initially until he was 5 months or so. Now we will put him to sleep in his bed then whenever he wakes up he will come into bed with us and he's almost a year. I don't see us stopping that any time soon either.
I co-slept with my daughter until she was about 11 months. I had a double bed and liked to have grown up time with my boyfriend after she went to sleep lol. That being said, she would still come into bed with me when she woke up in the morning. Sometimes she'd fall back to sleep, sometimes not. She stopped this year at 5.
My son is 3 1/2 months and I have no plans to stop any time soon.
DD is 3. She was sleeping in her crib just fine but now that shes in a big girl bed I have to lay with her until she falls alseep. She seems to be waking up a lot at night.If I stay all night with her it makes no difference either.
