My boys have never had problems with the O2. My youngest usually trys
to avoid using it. The reason to have them wear O2 is to prevent head
aches, etc. However, most people just fall asleep, so its not an issue.

The cool thing is that its easy to calculate kids O2. Their canualas
are regular (not oxy-savers) so they use twice as much O2. However,
their bodys are smaller so they use 1/2 the O2. It all equals out in
the end, I just set the system to give them the same amount of O2 I'm
using. If they start to bug each other, I just turn their O2 down and
they fall asleep. I've talked to C-5 drivers that do the same when
Marines are sitting in the back.

Corporate piltos do the same thing when the bosses in the back are drunk.
