I start to put them in carseat since they are NB. However, when they grow bigger and longer (taller), I change the basket type carseat to toddler's carseat.
So, even I drive them from here to there w/o helping hand, it'll be okay.
Chicco is good. Easy to fix, clean and it's spacious. The toddler's carseat can be used up to 3-3.5 yrs old...
