It will be interesting to see how many toddlers can still fit the Snugride 32 heightwise by age 2 or 3, especially if it has the same shell height as the SS1 (not sure about the shell height, I'm just wondering about it). My DD2 was too tall for her SS1 at just under a year old and approx. 21/22 lbs. It really depends on the child's height and torso proportions.
I have the weird kids. My 3 year old still fits by height and weight
and so does my large 17 month old (95% weight, 98% height)
However, I can't imagine keeping a kid in it past about 18 months. I know you can get it more upright, but it's still pretty reclined and low. I just can't imagine my 3 year old (or 1 1/2 year old) being happy in it as it's so different than a convertible.
How cool would it be though to have a sunshade that long RFing though? That's my biggest pet peeve with older RFing kids. They scream about the sun no matter what shades I've bought or tried. They just hate it.
