Snacks at School for Kids with Food Allergies

My son who has allergies started Kindergarten this year.  I knew he would see the other kids eating lots of things he couldn't have at both lunch and snack time.  His teacher was well-informed and thankfully kept an eye on him the first week any time he ate.  She saw a child give him something he shouldn't have two days in a a row and stopped him before it went further.  After several discussions about those foods making his tummy hurt my son hasn't had a problem since.

I pack his lunch every day so I know that he is getting foods that are safe for him at lunch time.  I also placed a small shoe box sized lidded plastic box in his classroom with individually packaged snacks that he could eat during snack time.  He has done so well with this and hasn't been upset when the other kids eat something different for snack time.

The picture above shows some chocolate cupcakes I made to keep in the freezer at school.  The purpose of this is to allow my son to have something similar to the other children for parties or if a child brings in cupcakes for a birthday.  The teacher can just take one out in the morning and it will be ready by snack time.

I did pack my son a special treat bag on the day of his class Halloween party.  I didn't want him to feel left out when other children got a treat bag. 

So far things have worked out really well for my son this school year.  I am finding that dealing with my son's food allergies while he is at school can be manageable through good communication with the school and through sending foods and snacks that are safe for him.

Do you have a child in school who has food allergies?  What are some things that have worked for you?
