Chris... I have seen photos here on CC with carseats installed. Certainly do-able; not sure tho' with the carseat YOU ALREADY HAVE.
I'll look for some photos; but it is certainly possible. I've seen photos with toddlers in car seats, with either earplugs or noise canceling headphones.
I'm wondering if the 'booster style' toddler seat, with the high back and that uses a lapbelt from a normal car would work, as opposed to a carseat that needs to have the strap go thru the back. He should be getting big enough to use the 'big boy' toddler seat. It isn't the typical old style booster that just was the seat, but rather a toddler seat, with a back, arm molding etc. I'll look for ya. Now if you're just kidding 'cuz your on 'daddy duty' then oh well, we'll catch ya sometime!
Stacey's going to Japan! wow!
