I also have a 3 year old and a 1 year old.

Mine started at 22 months. 

I have a modicum of hope that this one might not be living on a graveyard schedule. I almost never feel him at night, even when I get out of bed. He's super active in the late afternoon and evening and then settles down at night. My fingers are crossed, but I'm not naive about it.
