No actual experience with it but I don't see a reason it couldn't be done. If anything probably easier as kids usually don't produce as much body oil and for certain less BO. If you do use oils test first to make sure there's no reaction.
Personally I'd say just use vinegar. Not sure how you use it, but I use a
spray bottle for application. I know the
spray bottle can sometimes lead to vinegary fumes so be careful if they have breathing conditions, and of
course watch their eyes. Perhaps a better alternative would involve soaking a sponge in vinegar. Then again
water may be all that's needed. I would imagine using a cleaning agent daily wouldn't be the best idea due to the lower amount of body oils, he same thing actually goes for the elderly as well for the same reason
