With the new laws & needing to keep children in seats longer I would opt to buy one that goes right through. There are some out there now that do just that...then you don't have to get another one again later on. We got a maxi rider for DS1, fairly expensive & due to him growing very quick & being very stocky at age four we've had to buy yet another seat. Otherwise why don't you just hire a baby capsule for the first few months, then re-think what you want to do.
