I take my grandkids to work, 2 are school age, so just when their home sick from school or on a school break. The other 1 just turned 4 and I take him at least once a week. Have a room set up, feed him lunch and he has gone after lunch and taken a 3-4 hour nap, this is a kid who has not napped at home since he was 2. I try to check on him often, but at 4 he's capable of coming to where I am. He's also an escape artist, so the door leading outside is locked and has a chime connected to the alarm system.
If this is legit I feel bad for the parents, we don't always think in advance of safety issues.
I went to work with my mo growing up. I did have a room with toys, snacks, and such. But I never went 4 hours without anyone seeing me. I just think it's so odd, no one has reported seeing her. There are strip shopping on both sides of the road, it seems like there would have been people around during that time. It's also wooded, though. I don't know, 5 years old (JUST turned 5) seems young to not seek out someone for something for 4 hours. That's just such huge gap to be anywhere. I hope that she is found. Poor little one.
