Please teach your children to dial 911: especially if you are unable to dial it yourself at some point. It is a good idea to teach young children how to use 911 and the difference between an emergency (mom/dad has fallen and can’t get up, or mom/dad will not wake up) and a non-emergency (what time is it?).
Do not dial 911 for non-emergency situations. If you use 911 to ask, for example, when power may be returned during an outage, you may be tying up the line and preventing emergency calls from coming in.
