Bumps and bruises are a touchy subject with me. When my son about 18 mos old he climbed into a chair and got an apple off of the table. He then threw the apple up in the air and it came down on his nose at the corner of his eye. After a few hours he had a huge bump and his entire eye began looking bloody. I panicked and carried him to the ER where he was checked out and I was told while it would continue to look horrible for several days and would be bruised for several weeks he would be fine. By day 2-3 he looked like that side of his face had been beaten, bashed, smashed etc. Someone called CPS, along with police and reported possible abuse. Of course the 18 mos old boy did not learn his lesson, he had "I show," the officers what he had done, this time the apple being caught by the officer before it could hit anyone. Police were satisfied, but CPS still wanted to followup with his pediatrician before closing the case. His doctor simply told them, "He's a toddler, a very curious little boy, bumps, scrapes and bruises are his job." Case closed.
Also sad eyes and unhappy faces in photos do nothing for me either. Same kid would turn on the pouty face with sad eyes every time he was aware of a picture being taken and if you dared to take more than 2-3 pictures, you would get a full-on temper tantrum. He hated taking pictures. He's 22 now and still dislikes having his picture taken and has been known to throw a 2 year old fit about it.
Another thing, I have seen a few asking the question who would leave young children unattended in a running car (inhale) I have never done it, however, I see it happening all of the time. Running into the post office, going into convenience stores (at the gas pump with car running or not, but with keys left in,) just going to be at minute at Walmart, and (quite possibly the most popular) going through the drive-thru at whichever fast food to pull around, park, go inside to get extra napkins, ketchup etc.
About a month ago lady locked her newborn inside the car with her keys and phone inside at a storage facility and had to leave the car and run about 1/4 mile down the highway to a business to get help. Fortunately, she had left the car running with the AC on in the 100ish F heat.
As for leaving kids in the car to go back inside of the house/apartment, I don't know, it's like there's something about being at "home" that doesn't always register in the mind about the possibility of someone taking your car with kids inside. (Not that I am convinced of the claims being made in this case.)
That said, I had best slip back into lurk mode before I find myself in time out from my fingers typing what I would really like to say in regards to this entire situation.
Prayers that he is found safe tho.
