I personally wouldn’t go with a 22 lb limit in case you end up with a larger baby. You’ll (potentially) be replacing the seat months earlier than you would if you go with a standard 30-32-35 lb option. It just doesn’t give you the longevity that having the extra weight does. The other thing to consider is the Nuna Pipa is notorious for having install issues and often requires a rolled up towel or pool noodle to be used to get the correct recline. This is actually noted in their install manual!! IMO, a car seat shouldn’t require a pool noodle to be used for installation… it seems crazy to me. If you haven’t already, check out the Facebook Group “SEATS for kids discussion community”. There are certified CPTS (child passenger safety technicians) who can give excellent advice on which seats are recommended, which ones have issues (such as the Nuna) and help with fit-checks.

Honestly, due to the manual thread harness and the barely less weight (I wonder how much is the canopy? Bc the canopy will stay for the duration, but the inserts won’t), and the limits… (the pipa rx has 4-32lbs, 32”, vs the aire rx of 4-30, 30”). I would just get the regular rx. Basically it reads like the difference is merino wool, magnetic buckle holders vs inserting buckle holders, and some tiny amount of weight? Meh. Not worth $150. Edit: I wish they would have redesigned the no rethread harness head cushion (since it sometimes caused fit issues for the littlest babies and kiddos at the larger end with big heads) rather than switching to a manual rethread.

There’s a third limit to infant seats - their heads must be an inch or more lower than the top of the shell when buckled. And it seems like most infants hit that limit first. Both of mine reached it around 7 months. And they were only about 28-29 inches tall and under 20 lbs at the time. They just had long torsos as babies. So it’s possible the others just reached that limit or didn’t want to lug the seat anymore. I’d check whether she’s past that limit and move her immediately if she is. I don’t know of any convertible seats that don’t take up more space than the infant bucket seat while rear facing. Since she’s over 1, you can at least position it a little more upright which sometimes saves an inch or two. We use and love the Nuna Rava, any of the Britax clicktight seats are also great for being easy to get a proper install. There’s really so many options that a lot comes down to your family’s priorities in a car seat. More on reddit.com

Yes. My baby was 22lbs and 28in at about 7 months when I switched him from his infant seat to our convertible. He was much happier! More on reddit.com
