James weighed 39 lbs on a scale recently (and his car seat, like most, allows rear-facing to 40 lbs), so after all our holiday travel (when he and Cora watched many DVDs rear-facing together in the car), we ordered him a new car seat. Yes, he could have stayed in the
Britax Boulevard 70, just flipped to forward-face (since it goes to 70 lbs forward-facing), but we wanted to move Cora up out of the
Britax Diplomat anyway. (The Diplomat is a retired model, a smaller convertible car seat, and goes to 35 lbs rear-facing - so technically Cora has a ways to go before she'd outgrow it, but since we want to keep her rear-facing to 40 lbs, we figured we'd go ahead and move her up to his Boulevard now. The Diplomat can only be used forward-facing for an additional 5 lbs anyway, to 40 lbs, so it really is a small seat.) We decided to go with a combination harness-to-booster seat, the
Britax Frontier 85 SICT, that allows harnessing to 85 lbs (and booster use to 120 lbs). We, of course, have no way to predict the future of where James will be height and weight-wise throughout preschool, kindergarten, and elementary school, but we know this car seat will last him a long time (probably beyond it's expiration date).
It's been interesting having him forward-facing... We definitely have a backseat driver now. He tells us when to stop and go (at lights and stop signs), warns Cora about upcoming cool things he sees, and asks even more questions than before as we drive along. And he's even better with giving directions to his house now that he can see where he's going (as opposed to where he's been). The biggest bonuses for us in having him forward-facing is that we can now actually walk into the van from the back seat (before, the two rear-facing car seats blocked both entrances, so we had to jump over the center console up front) and we can actually hear every single thing he says (no more voice lost to the back of the van). So yes, we are very happy to have moved him up (but also very happy that we were able to keep him rear-facing and extra safe for as long as we did - almost 4 years!)
As for the new car seat, James LOVES it. When we sized it for him, we did a "crash test" in the living room that cracked him up (we were just happy that jostling him around in the seat didn't cause him to budge an inch, and his head was well protected with the SICT). The cup holders are super cool (for cups, as well as small toys). And the fact that he is now forward-facing and no longer tilted at an angle means that he sits up higher and can see out the windows much better, which makes him super happy.
The only issue we've come across is car naps. The lack of angle makes it hard for him to get comfortable and find a way to rest his head, and there's now no place to rest his feet, which makes him grumpy. Turns out though, that he CAN sleep in the new seat just fine, once he acknowledges that he's tired (instead of pouting about nap time).
He suddenly looks so small to us again, in this big new car seat...
