Do you have anything in your contract/policies regarding...

Here is what it is stated in my policy manual:

First Aid:
I hold current first aid certificates, and are ready to perform care when necessary. A complete first aid kit is available at all times, including on field trips etc. The children’s emergency info/consent cards are kept in the first aid kit at all times, as well I usually carry our cell phone with us on outings for use in the event of an emergency. In the event a child needs emergency medical attention an ambulance will be called, and then the parents - to allow them to meet the child at the hospital as soon as possible. Any serious incidents will be reported by filing a serious incident report immediately.

Injuries:
I will supervise your child closely in an attempt to prevent injuries, but accidents resulting in injury do occur. I have been trained in first aid and CPR and will follow my training. If the injury is minor (requiring only a band-aid or ice) I will tell you about it when you pick up your child. If it is serious, I will call you and may even suggest that you take your child to the doctor or emergency room. If an injury is very severe, I will call 911 for assistance before I call you. If I can not reach you, I will call the emergency contacts listed on your “Child Information Record” (Please remember to keep this card up-to-date).

If I can not reach you, I will call the emergency contacts listed on your “Child Information Record” (Please remember to keep this card up-to-date).

I send out an email to my daycare parents every 6 months to see if any contact info has changed. Some times things change and with busy schedules, parents might forget to inform us.
For me, it just takes a few minutes to send out an email that I have marked as a reminder for me when the date comes up, that if there ever is an emergency I won't be scrambling.
