Alot of this question comes up : Didn't they check the house already?
Well, little boys that I have known are GOOOOOOD hiders!
I had a family living with us and they had a 4 year old boy and OH DEAR LORD can that boy HIDE! After school, while me and the boy's mom were busy in the kitchen cooking and cleaning up, one of us will go back and forth checking on the kids watching cartoons (there were 4 kids from 2 to 6 years old plus my daughter that was only 4 months old). Well, ALOT of times we go to check on them, a little sneaker is MISSING! We would be looking from top to bottom, through everything for him but still cannot find him. Think of this, HIDEN IN PLAIN VIEW! The boy can hide in a corner, under the bed, or in the laundry room, balled up to a point where u cannot see any part of him but his clothes, makes u think ur seeing a pile of clothes. He is BARELY hiding! There was one time when ALL of us were home (even the dads), the dads were supposed to be watching the kids while us moms were doing laundry. That little boy vanished without a trace. We went looking for him for HOURS and couldn't find him. Sure enough, he was under the bed of his parent's room, balled up in between a whole bunch of other stuff under there.
OH boy, was his dad MAD! I dont think he was able to sit down comfortably for a while!
I was able to break his habit of hiding in strange places. I asked him why he hides, he says he's scared (he has problems mentally). I told him that there is a table next to the couch, that is the ONLY place he can hide. Sure enough, whenever he felt he needed to hide, he will hide right under that table and we always knew where to look and after a few weeks, he stopped hiding. After they moved out, from what I heard, he has started hiding all over again and once hid for 2 days while mom and dad couldn't find him. They called me up and asked me to help them out. It took them 2 days to find the boy, while it only took me a few minutes to find him, UNDER A TABLE NEXT TO THE COUCH.
