Adjustable Harness

My 6 month old son is 22lbs and 28 inches. His torso is long so which convertible car seat is best?

He grows fast and needs something with adjustable harness height and something that can recline rear facing and slightly recline forward facing. I have looked into the First Years True fit and the Graco MyRide, but I want to be sure it will work the best before I buy it online.
Zaiden's Mommy: Ayden was actually only 7lb 10 oz when he was born 2 weeks early on March 23rd! Their birthdays are so close! He is very proportionate and has turkey legs so I'm not sure where he's hiding it. Maybe in his big melon? lol
Thanks!

My son was 27 pounds 12 ounces and 30 inches long at his 6 month check-up. Don't you just love having a big baby?

Since he's been so large all his life we switched to a convertible seat at 2 months! We got the Evenflo Triumph and he fits just great in it. It has all the same crash test ratings as the absurdly priced Britax and is VERY easy to use. It's pretty bulky but still fits in my little car. I love it and I would definitely recommend it. Increased! It is rear facing up to 35 pounds and forward up to 50 pounds. And don't worry, your son won't always grow so fast. He'll slow down one day!

Good luck and congrats on your big ole boy!!!
