hi sifus -

i've got few questions :

1) can we put the newborn(between 1-14days old) into the carseat? i need to travel 3hrs journey
2) there are few models that can't fully recline to flat or the design is a bit curve..can the baby sleep in the not flat position? will it hurt the back or spine?
3) do you need to buy another carseat as your child grows-up?

appreciate your wise answer/advise. thanks
