We absolutely love this carseat for our daughter. She is in the 10th % for weight and length. Surprisingly, the infant car seat was no longer comfortable to her around 6 months. It didn't have much cushion, and her legs dangled out quite a lot. So, we decided to switch her to the convertible seat at 7 months. I picked our infant seat (cybex aton 2) because it has the steel leg. I am very concerned about safety, and would literally spend nights awake worried about car seat safety. Sure, they all meet regulations, but if there's something I can do to provide my precious baby a bit more safety, I'm all for it. Meet Maxi Cosi Pria 70. This is the cadillac of car seats my friends. Not only is it incredibly safe, with the head rest that will keep your child's neck from snapping, but it is like riding on a cloud. This seat is so plush, and comfortable, my colicky baby immediately falls asleep as soon as we put her in. Another plus, is that the seat does not sweat a lot, which is important here in the DC summers. The seat does take up one whole side of my Jeep Cherokee. I think any bigger of a seat would not have fit! When researching it I found that it is not as tall as some of the other ones (radian) so that's important if you have a compact car or suv. We also bought a second seat for Grandma's Acura RL, and she has plenty of space for the seat there as well. Also, Grandma babysits full time while I am at work, and it's easy for her to put baby in the seat as well. I have peace of mind knowing that it's simple for her. The only thing is making sure Grandma tightens it enough, but that's for any car seat I believe.
