There are several brands of electronic muffs, and I would choose some that fit the child. Stay away from el cheapo, and get a reliable brand.
The in ear protection is not great for kids because their ears are so small.
My kids put theirs on the second my gun was loaded. And kept them on until it was unloaded.
It is my understanding that a child's ears are more sensitive to damage than an adult's are.
