Can E4 be used for Kids

[HD87]

I suggest you use masked format for children.  They can hear ultrasonic, and it may be annoying.  Hybrid is most likely going to be a shock and overload.

Thanks @Shannon just purchased E4, and I will start with the masked version and see how that goes, just one question, do I follow the same listening instructions for a child too, or should I tone the number of loops, and days down a bit?
