Nima can be used by anyone as long as they have read the instructions and are aware of limitations.
It's up to you if you want someone else to carry Nima for your child. You'll also have to ask people at schools or daycare if they are willing and able to use it, as individual school policies vary. We recommend everyone using Nima do a full review of the Nima Gluten Manual.
