I am new to this forum. I own both the ultimate zapper and Don Croft's basic and terminator models. I was wondering if anyone has any advice for using any of these with children. I have a nine month old and a 4 1/2 year old. Both have GI issues. I have been doing the ultimate zapper with the handholds and footpads on my 4 1/2 year old for 45 seconds/20 min rest/45 seconds/20 min rest/45 seconds/20 min rest once daily for about a week or two. She has had some minor improvements in bowel function but not resolved. Is this enough time enough cycles with the ultimate zapper and/or would the basic or terminator model of zapper work better for a child and if so how long to leave it on?
