If you have ensured they fall asleep independently since 3 months and would never consider lying with them then this isn't the thread for you 
To those who have done this... my son is 4.5 and we still lie with him to fall asleep, as a baby he fell asleep independently but toddler years put an end to that and he has fallen asleep with us lying with him ever since.
On one hand I love the cuddles, and I know it won't last forever and he sleeps well once he's asleep so I haven't ever really minded. I guess I hadn't really thought maybe it's unusual we still do that but perhaps it is now. I'm not sure how to stop? He definitely wants us there, he asks for cuddles etc and I just don't know how to ease out of this without him getting really upset, I just read about gradual retreat but he has a mid sleeper with a tent over the top so he won't see me if I'm not in bed with him and he wants us to cuddle him..
If you did this past 3/4, how did you eventually stop? Did they just grow out of wanting you and tell you to go? Did you train them somehow? Was it brutal?
