feval, when baby is very yound can carry, but when they get more mobile very difficult to handle, somemore they have itchy hands and feet, will want to grab this and that, not very easy to handle.. maybe dun get those infant car seat, cos those the bahy really will outgrow ery fast, and not cheap also. you should consider getting the convertible car seat, can use from infant till very big, some can even convert to boaster seat.
and it is regulated, they must be in car seat, of cos taxis bo bian lah.. i remembered when they first regulated it TPs were checking, but now maybe now not so active in catching. but if believe safety first lah, cannot give in to the child all the time, like they dun wan to sit in car seat then allow them not to. then if next time they dun wan to buckle the seat belt then we allow them to also meh?
