I heard from another MoM whose babies came home at 4 1/2 and 5 1/2 lbs (roughly) that she had to buy a different temporary carseat(not a car bed). Snugrides only have 2 different shoulder strap height adjustments and even the baby over 5 lbs. didn't fit properly. She bought a different carseat (not a car bed), that had 4 different adjustments and recommended waiting to take the snugrides out of the box, but I really wanted to get them installed and inspected before we had the babies!  I wondered if anyone here ran into that problem?                  
                             
        
Re: Anyone else have to change carseat (brands?)
That's what happened to us. They gave us a list of seats with shorter strap height options. We went to Walmart and bought the cheapest one. Mason used it for two weeks. Wyatt used it for one week, just home and then once to the pedi. Then they fit in their Graco Safeseats. We knew we wouldn't continue using those cheap seats: they didn't even snap into our Graco double stroller. So I don't regret going ahead and getting our other seats out and set up.
eta: My boys were 6 lbs 10 ounces and 6 lbs 6 ounces at birth, so I was really surprised we had a problem with the seats!
