Geoduck – I just dug out the packaging for the waterflosser and it is a waterpik! Should have checked that before I asked Larynxa! 
It’s battery operated (rechargeable) and has different tips – one is designed for teeth with braces so would be good for your children.
There are two pressure settings so there’s a gentle one for sensitive gums.
It was expensive even when in the sale. But I have no regrets now that I have got used to it.
I shall stop here before someone thinks I’m collaborating with John Harrison! If any readers happen to work for waterpik promotions, please just give a donation to this site!
Gross tale geoduck about your flosser at breakfast. It reminds me of one time I was abroad. On the dinner table was a jar of wooden toothpicks. A lady sitting opposite me took one and picked at her teeth for ages. Then she replaced the used toothpick back in the jar for someone else to use. Nice!
