It is the perfect combination of crap.
Cyrille Rossant may save a lot of lives, in both parents and children, if this becomes common knowledge.
Just to defuse this a bit. My #4 used to collect skull fractures. He'd slip away in a nanosecond and would be 50' above us two heartbeats later. We put him in a padded helmet for a year or so. It stayed on sometimes.
As an adult he can still disappear in an empty room.
