I have been meaning to try my friend's kids in my husky so that I can appreciate how long this seat might work. I really appreciated the postings of over 40 # kids in seats, but I wanted to see how kids I knew would fit. The oldest is almost 10 and very tall (although alot of leg), and maybe 65#. She just fit, and commented that it was really comfortable. She said that she would prefer it to no seat, and she has been out of a carseat since she was 2 or so. When she went back with her mom she just raved about how great the seat was, and how she would like one! The second child, 6, was actually in a booster tonight, because she wanted to since her 3 year old sister was at home. Unfortunately, she had the shoulder belt, behind her back. I explained to her for the millionth time, why she should not do that, and she agreed. Her mom said that it was a real challenge and I suggusted she try the regent to remove that hurdle. We will see!
