Can someone explain Step 1 and Step 2 carseats to me?
Hi there,
I am trying to start registering for our twins and I am very confused about carseats, especially the "step 1" and "step 2" models. If the step 2 models also work for infants 5 lbs and up... what is the point of getting a step 1 model which is only good until the babies reach 19 lbs??
