No, A.K, you didn't overreact. You DID the RIGHT thing. It is NEVER okay to leave a small child in a car unattended----regardless of the temperature or windows being cracked a bit.
I would have called the minute I saw a 2 or 3 year-old in a car unattended. A messed up nap schedule for one day is nothing compared to the potential dangers in situations where helpless children are left alone.
I thought everyone understood this, but apparently, there needs to be more community-wide education in this area.
Temperatures inside vehicles can rise to dangerous levels very quicky, even when it seems relatively mild outside. A child this age does not have the capacity to recognize the danger and rescue himself. Nor does he have the capability to protect himself from someone with criminal intentions.
This mother needs a wake up call, as do your co-workers. So many children die needlessly every year because they are left unattended in hot cars or in other potentially dangerous situations with no supervision or possible ways to save themselves.
About your co-workers' concern for causing trouble for the family???? I truly hope they don't have any small children or grandchildren in their care. That level of ignorance is just frightening.
Please, do not feel badly. You may have saved this child's life by getting his mother/caregiver the childcare safety education she desperately needs. If you'd just alerted the store, she'd have gone out and got him. Fast forward to the next time, when it's 88 or 95 or whatever outside and she decides to leave him again. Only the next time, maybe it wouldn't be you walking by.....maybe it might be one of your co-workers, who is more concerned with causing trouble for the parent than for the welfare of the child. Or maybe it might be a predator looking for just such an opportunity.
Most likely, after a period of evaluation, unless there are other serious concerns uncovered by CPS, the child will remain with the family. The parent will be followed by a case manager for a time and will have to take some classes, which obviously, she needs.
Bottom line: Saving a life or protecting a life from serious danger ALWAYS takes priority over any other concern.
You did the right thing, and hopefully your story will help educate people and encourage people in future situations to get off the fence of indecision when a child's welfare is at stake.
Best to you and your family.
