"Younger children, especially smaller ones don't have the correct position in a car with just a normal seatbelt on."

Ok i get that there are a few small children in New Zealand and maybe they should have to use a car seat for a bit longer but is it really necessary to change the law to enforce all children !! why not change the law to children under a certain height and weight ?

This really makes me angry as my girls for example are big girls i don't even think they will fit in a carseat when they are 7 and if i was to put them in the car without a carseat i could get fined $1000 !!

Im all for parent safety ( in fact you can ask my mum she thinks I'm OTT cautious ) but i believe we as parents should be able to decide when we think our child is old enough to sit in the car with just a seatbelt

I feel like parenting is becoming more and more controlled by the government .

People say that we live in a much more dangerous world but i wonder if in fact we live in the same world we just get told more and more things are bad and that we shouldn't do certain things shouldn't eat certain things , children are not even allowed to climb trees anymore !! we are wrapping our children in cotton wool , how do we expect them to survive in the real world ?
