Gemini,
when there's child in car, it's good to have child lock on all the way. Safer mah, especially you dunno what kind of pattern they will suddenly give.
Adeline,
Try to sweet talk, coax, show Kim how Kathlyn guai guai sit in her carseat.
Bring some toys, biscuits whatever to keep Kim entertain during the journey.
Or play her favourite CD and get her to sing along while clapping her hands.
You have to link her mind once in car, she has to be in carseat. At home, link carseat to car bla bla. What my colleague did last time was (his daughter like Kim very stubborn, refused to be in carseat), he brought the carseat home. Play and pretend. Like pretend to drive, ask his daughter to "get into" the car, buckle up then he drive. "Reach" destination, then his daughter "get off" the car. Then he kept telling his gal. No carseat no gai gai etc.
Carseat is always advisable to have. I rather pay for the carseat than to be sorry. Even if you or yr hb may be a safe driver, it doesn't mean others are safe driver.
Try to get a carseat during sales to save some $, or any colleagues/friends have pass down ones (make sure no accidents before).
Booster seat is only a "seat" that helps to increase the height of a child. It is using the car seat belt for buckle, just like us adult. Not sure for kids cos unlike adults, they won't know how to react (adults dun even know how to react, let alone a child!).
lilboymum,
I saw one blog before, it's a boy who got killed w/o a proper 5 point harness carseat. It was really sad!
I think the current carseat that Jaslyn is using can use up to 45kg, if I remember correctly. Yes, like CY's one, can convert from infant to child then to booster seat. But hor, the booster seat super big. So when it comes to the day when Jaslyn is going to upgrade to booster seat, I will not convert this current carseat since I bought 2 booster seat earlier.
