yes,u should put your child in the carseat in case anything happen,but the price quiet expensive.but still,to compared with your child life,its really worth the money..

My son (soon to be 15 months) cannot sit in the car seat for more than 5 minutes. Will struggle to get out. If we force him to be in there, he will cry cry cry... sigh...

I agree with you.  My carseat has the side impact feature too.

Which comes to the next question, the locally made ones like Sweet Cherry..i wonder if theirs are as compatible with the imported ones?  For the fact that since in overseas, it is mandatory to have car seat for children, the car seats manufacturer over there will have to undergo tests to make sure that it meets all the safety requirements.  Whereas, since in Malaysia it's not the law, manufacturers here may not manufacture the seats up to par, though it's cheaper.

Some people don't use seat belts and don't use car seats for their kids.  Yet kids all grown up and everybody still alive.

The question is - do you feel as lucky?  Better safe than sorry.
