OT - Car Seat

[happymom]

My son rides in that same seat!

You need a "combination seat" (not a convertible, that would be for rear facing).

I recommend the Harmony Defender or Graco Wayz. My son is little like her, 38" and 31lbs - he is 5. I like the Harmony Defender seat because it can turn into a booster at 30lbs and 34" instead of 40 (he probably won't hit 40lbs until age 8-9)

"They" say it's safer to keep in a harness until age 6 and 40lbs, but I decided I will make my own decision when it comes to that.

This is the Harmony Defender seat. The headwings are adjustable and the straps are adjusted by a lever at the top of the seat.
He could harness in it until 65 pounds if I want

The seat you have is a very poor design for booster belt fit, and also it assumes all children should hit 43" at the same time they are 40lbs. It's very poor overall and never a recommended seat.

I never saw how old she is, that is a huge factor in addition to size.

Harmony defender, Evenflo securekid, Graco tranzitions/wayz, and the Evenflo sureride all go to 65 lbs in harness mode. All but the sureride have a booster mode after the harness is outgrown. They can each be found for around $100.

Here's my thing with boosters...make sure it has a nice big, easy to slide through, shoulder belt guide. Otherwise it's useless. The seatbelt needs to freely retract if they lean forward for a moment to grab something then sit back.

This is a common problem on combo seats.
