Put together an emergency bag for your child that you can leave with your childcare provider.
In a large ziplock bag place a warm outfit one size bigger then your child normally wears along with a few non-perishable snacks. Include a laminated page of pictures of loved ones and a special toy or blanket. Give this to your child's care provider. In the event of an emergency, your child will have a warm change of clothes, a few provisions and most importantly, pictures to reassure him.
