Hellobee Boards

My LO is 4 (turned 4 in June) and weighs 29 lbs. She is in the 20% or so for weight, so she isn't insanely small.

One of her little girlfriends just turned 4 and weighs 42 lbs. and I definitely don’t consider her “big” or bigger than the average 4 year old in the preschool class (there was one of those “all about me” boards at her birthday party a couple weekends ago; I’m not a stalker of this kid lol). So….could last until your LO is 4, or might not!

My DD turned 4 in June and is 31 lbs. That's 18th percentile for a girl her age. She's only gained maybe 3 pounds since this time last year, so for her, I'd expect that seat to last a LONG time. Can you look on a growth chart and track how you'd expect your LO to grow based on the current percentile (if it's stayed steady)?

Honestly, from my experience, unless the $80 for the two seats will be a hardship for you, it's worth it to get them even if you donate them a year from now and save yourself the hassle - I hate lugging baby gear in airports!

she turns 5 next month and weighs just at 50 lbs but she's about 80-90% for height.

4.5 year old weighs 35 lbs.

I did something similar -- we basically now have two cheap, lightweight carseats that we only use for travelling (so that we don't have to re-install in our cars when we get home, in case they get damaged, etc). We originally had just the Cosco Scenera for DD1, but now handed that down to DD2 because she outgrew the infant bucket. For DD2 (4y), I got the Evenflo Chase. I'm also pregnant with LO3, so eventually we'll pass both of those down again, and I'll just get a booster (high-back or just regular, depending on age/size) for DD1.

ETA: to answer your original question, my DD1 has always been around 50% for height and 30% for weight. She is currently 37lbs at 4.3y. But weight gain is pretty slow at this age!!

My daughter is almost 5.5 and she weights right around 40 lbs.

My 3 year old weighs 42lbs

At a little over 4.5 she is 42 lbs and 42 inches. She's usually in the 85th-90th percentile

DS is 5 and weighs 35lbs.

@Anagram: my 4 year d (5 in December) weighs 37 lbs. she weighed 34 and her 4 year checkup,

We did something similar for travel but i wanted to echo others to check height too. Some of those 40 lb seats are for 40" or less and my LO was past that by 3 1/2 if not sooner. So one bigger weight/height limit is probably smart for you!

4 and he weighs 30 pounds, but is a tiny wisp of a thing.

my 3 year old had a huge growth spurt in the last few months and weighs 42 pounds. He turns 4 in about a month!
