Hmmmm. Well, I kinda thought the board thing wasn't a good idea.
We never had the head slumping problem with the MA in the same spot, so I'm pretty sure it's the headrest that's the problem. Ds is 30 pounds, and only has 3 pounds left for rear facing, so turning him rear facing would only be a temporary solution as far as the head slumping is concerned. He is near enough to the limit that I'm not going to try to force him to sit rear facing now (he was rf up until he turned 2). There also isn't really room to put it rf behind the driver's seat of our van. The front seat would have to sit too upright for the driver's comfort.
I had thought about switching the seats, but I wanted to use the Blvd for the ff kid because of the added side impact protection. Also, ds was so excited about getting a new carseat (as opposed to the baby getting it), that I'd hate to switch it on him now (but I will if no other option presents itself).
Our van has bench seats in both the second and third rows, and there's no way to recline the seat back even a little.
Does anyone else have any other suggestions, before I resort to switching the seats? His head really slumps a lot... his chin touches his chest. That just can't be good.
I'm now wishing I'd bought another MA or Decathlon instead.
