How much longer RFing?


New member
We have a britax advocate 70cs and I want to be able to rf my son till he's 4. He's going be turning 2 this month and is about 25lbs fully dressed and his seated height is 12 inches. Do you think we would be able to make it 2 more years rear facing?

Best thing to do is post a picture from the side of the top of his head in relation to the seat back.

Most kids do not make it rf to 4 in the britax seat(not saying none do). Both my kids outgrew them between 2-2 1/2yr rf.

you could post a pic though

It's really hard to know. If your kiddo grows like mine did, then they'll have leg growth and then torso growth, back and forth. That combined with the Advocate having a shorter shell, I would guess making it to 4 would be unlikely.


My dd is 21mo and has a 12" torso too. She has 5.5" above her head in my new gen Roundabout. If she stays on the growth pattern she's been on since birth she will make it to 4yo rf in it. My middle child who has always been in the 90th percentile would have made it to 3y8m rf in the new gen seats.

21mo 31" tall, 19" seated height, 12" torso

3y7m, 38lbs, 40.5", 14.5" torso, 22" sitting height. In this photo he has 1.5" of shell above his head.

I think you will make it to 3 and likely past. I wouldn't have high hopes to make it to 4 though.


I'd say you have a fighting chance of making it to age 4, or if not all the way to 4, probably very close. It looks like maybe 3" of torso growth before he is to the height limit, and if he grows somewhat evenly that's about 6" of overall growth. According to the CDC growth charts, an average boy will grow about 6" between age 2 and age 4.

I give it about a 50/50 chance. Initially, my thought was no, but he looks short in the body so maybe.

Can you see them now?

Yes, they're there now :)

I see about 4" above his head, so 3" of growing room. It all depends on how he grows in the next two years. My middle son hit a huge growth spurt in his torso between 3 and 4. He outgrew our Roundabout at 3y8m and then went on to outgrow the Radian rf at 3y10, both by height! You should easily get to 3-3.5......4 stands a chance but it is just soo hard to predict an individual child's growth.
