As for my children, thank God I've trained them to be in car seats from day three they were borned upon leaving the hospital. Up till today, they sit nowhere but in their car seats courtesy of MaxiCosi. In fact, they are more comfortable in their MaxiCosi, able to sleep long hours during any journey than sitting freely in the rear.
Zareef in his MaxiCosi's Rodi (Stage Three) even though he keeps on saying that he's a big boy now and doesn't need to be strapped to one. Not yet my boy, not yet.
