I've had this happen a few times with both cribs and high chairs. The toddlers aren't reset because in many cases that would put them in a place where they cannot get back inside or into a room where the fun stuff is without being carried (steps outside from the reset point, the bedroom and other fun places are all upstairs, or up an elevator, etc.) Don't all of us remember being "behind bars" at that age and just wishing we could squeeeeze through and do something fun while the adults are all asleep or not paying us any attention? :)
