Another thing that can be hard is the Easter eggs. If you have your own Easter egg hunt you can control the candies being put into the eggs. It is best to start with fresh new eggs that have never been used to avoid contamination. If you are going to another hunt, it can be difficult because there will most likely be chocolate. Yes, you could let them find the eggs but just taking out the chocolate may not be a great idea. Typically easter candy is covered in foil and not sealed. The best option in that situation would be to either be sure that there will be safe candy or bring some to trade out for. That is what we do for Halloween. We separate the safe from the unsafe or unsure. Then we let them replace it with allergen free candy that we had bought ahead of time. I also hand out candy that is the BIG 8 free every year.
If you have any questions or would like some more pointers, please let me know!
