I found these labels from Label It or Lose It that are fantastic! They make specific food allergy warning labels as well as a variety of other labels. They are even dishwasher safe!
I ordered the allergy warning labels for Bubs and the regular stick-on labels for GirlyGirl.
The allergy warning labels allow for up to four allergies to be listed in addition to your child's name. They are bright yellow which draws attention to the warning. I have stuck these on water bottles, lunch boxes, backpacks, etc. They have been through my dishwasher over and over and have yet to come off. These things are durable! (I must say that these adhere much better to solid surfaces than fabric surfaces. This type is better for short-term fabric use. They do make specific iron-on labels if you need a permanent label on fabric.)
The personalized stick-on labels are smaller and more subtle. They are also dishwasher and microwave safe. There are a variety of images that can be chosen from to be placed on the sticker. I chose to use the medical alert symbol. Where it prompted me to enter a name, I typed her name and "Peanut Allergy" so it was all listed on the label. This type of label comes in a pack of five colors. GirlyGirl loves the variety to chose from! I have stuck these to her water bottles, lunch box, and backpack, and more as well. (Same goes for fabric use as above.)
What a great way to send the message that your child has a food allergy! The kids love these stickers. GirlyGirl wants to wear them on her shirt every time she goes to a party. So cute!
I would definitely recommend Label It or Lose It as an easy and fun way to communicate your child's needs.
