Our little guy is going to be 20 months for our next flight. We found that he wouldn't stay in his car seat on the last plane ride, so I thought I would give the CARES harness a try since he falls in the weight/height range for the harness. He is 34 inches and 28 lbs. I was thinking that I would just use the harness and have Grandpa buy a car seat to store at his house so we wouldn't have to deal with it on the plane. But I'm reading some archived threads where parents are saying that their kids didn't fit well in the harness until age 3 or so. I'm hoping to hear from people about what height/weight they found worked in the CARES instead of age (since that varies so much).
