Parents answer your freaking phones! Your child may actually freaking need you.
My mom works in a daycare center. They just sent a 3yo to the hospital due to fever seizures. They noticed he had a fever early in the day, (his mom probably knew he had one but sent him, anyway) and the daycare can't give him Tylenol without the parent. Well, they call and call and call all the numbers on this child's list, and no one would answer. Mom thinks that the mom didn't want to answer and have to actually come get the kiddo.
This poor baby's fever just kept going up. He ended up convulsing and they had to send for an ambulance, all because the mom or dad didn't answer their phone or check it for HOURS. The kid went to the hospital and the parents still don't know.
If you work, please make sure the number you give as an emergency contact is a number you will actually answer! I understand needing to work to make money, but that is ridiculous!
