In our car seat safety class, we were told that convertible car seats are perfectly safe with newborns.  The only difference between an infant car seat and the convertible car seat is the convenience factor– infant car seats are easier to take in and out of the car. So if your son is 4.5 months, I don’t see why it wouldn’t be fine to switch now if he’s outgrown the infant one. Especially if your car can fit the Britax Marathon facing backwards.

By the time DS was 5 months it was easier to just take him out of his infant carseat when we got to where we were going and either carry him or wear him so I would think you’d be fine to have the convertible carseat as long as you’ll still have it facing backward.  We plan to switch to a convertible carseat around 11 months old and continue to have it facing backward.

@red_seattle:  That’s really interesting because I was told the opposite in my carseat safety class (i.e. that infants are safer for infants, although convertible car seats are acceptable).

ETA:  I think I misread your post.  I think you’re saying that you learned convertible seats are acceptable for infants?  That’s what I learned, too, but our instructor stressed that acceptable does not equate best choice.

We switched at almost a year simply because we were going on a really long road trip, and we thought the convertible seat would be more comfortable.  We still had some room on the weight and height requirments, though.

Personally, I think I would wait until my baby was at the max weight or height before switching.  Babies grow a lot in the very beginning, and then level out some, so your son might actually have a couple months left before reaching the max.  By the way, you DO have a big kid on your hands!  Wow, lol!

We’re probably going to have to switch soon too. Our carseat goes to 22lbs and 29in as well and babygirl will probably outgrow height before weight. She’s only about 14lbs right now so I think she’ll be alright in it but she’s 25.75 inches and has averaged about an inch a month so I assume I only have 3 months left. We’re going to see what her stats are at her 6 month check up and then go from there. Like you I’m kinda nervous about putting her in a convertable carseat already.

I have the Graco snugride 35, and I really like it.  With such a big (little) guy, I think I’d err on the side of caution and go as big as I could find, lol!

We have the Graco SnugRide 35 Infant Car Seat and it still fits our son. He was  20 lbs at 4 months, and at his 6 month check up he was about 23..so we have a little while until we have to switch 🙂

@pansyshell: So I’ll be the odd woman out here and say that we started out using a chicco keyfit 30 with my son and we switched when he was 2 months old to a convertable seat and we haven’t looked back since. I think our sons are close in age/size. My son never liked the infant seat.. he was always too hot, couldn’t look around, and would SCREAM the entire time we were driving. We switched to the convertible seat which reclines a little bit and has an infant insert and it has been great for him.

Argh, I had a long response but accidently closed the screen and now I have to hurry on out soon (i got permission to go to my child birth class– hooray)– so I’m being brief here.

@Mrs. Spring: and  @pansyshell: I’d go with whatever you feel comfortable with and whatever you learned in your car seat safety class, but according to our instructor and my research, the reasons that some say infant car seats are safer are fit & ease of installation. It’s not because they behave differently in a crash. (Both surround the infant & child in a crash, and if the child is strapped in correctly, both will prevent spinal cord injuries.) Some convertible car seats don’t have straps that properly fit a newborn or small infant, and generally, infant car seats are easier to install. But pansyshell can pop her son into the Britax Marathon she owns to see if he fits (so that problem is easily solved). And as for ease of installation, you can have the car seat inspected, and of course– read the car seat manual & your car’s manual to be sure you get the installation correct. 

So is one safer than the other? In this instance, not from what I’ve found. But if you feel more comfortable with the infant car seat (and thus, you’re more likely to use it properly), then by all means, I’d opt for the infant one.
