Part of the problem is that children aren't heavy enough for a one

different attitudes to the water. A shorter child will tend to float
differently with a PFD than one who is tall or one with long legs. A
child can also change very rapidly rendering a PFD ineffective in
terms of fit - what may fit this January, might not fit in July.

Cement might be better. Lead can be harmful to developing children.


Cement?

You mean like the "Fullers earth" ships made in WWII ?

No...more like minature versions of the type our neighbourhood 'made guy'
used to dispose of victims.
Small 5 lb versions might be enough to offset the lifejacket flotation keep
a child perfectly vertical in the water...as per Gene's theory.
