Could it be the French approach to baby storage?  One thing that strikes me as a parent living in France is seeing all these three and four year old kids strapped in to push chairs at all times with dummies in their mouths.<p>Our kids will be running around feral, trashing the place and getting disapproving looks from the other parents, who seem to be spending the whole of their effort suppressing their kids natural desire to play.<p>Granted, they&#x27;re well behaved by the time they get to school.  But thus far we haven&#x27;t been inspired to emulate that treatment.
