I'm a bad mom. I turned my DS around right at a year. because otherwise we'd never go anywhere at all. He HATED facing backward. now (13 mo) he's facing forward, in the center of the gigantic SUV, and he's happily chatting with me and I can grab his toes and tickle while still facing forward & watching the road. Our ability to go places is amazing now. The best part? he can now recognize his neighborhood. I can describe to him here is so & so's house, here is the cemetary, here is so and so's house, our house is next! and he gets very excited when he recognizes various things as we get closer to the house. He loves pointing at the trucks through the windshield, etc... the difference is just amazing. He actually talks constantly about what he sees, and he's at least getting the stimulation he didn't get while facing backwardm staring at the back of the seat, screaming his head off.
I know, I know, backward facing is the best, but it was either that or never going to the grocery store. I put up with the screaming for a year. I talked with his Dr. about it, and she said that it was fine to turn it around, and I shouldn't worry about it. I do worry. but I also reason that in reality, it's safer for EVERYONE to ride backward, not just little kids. If I had a kid who didn't need constant stimulation, then he'd probably still be facing backward.
when we were kids, I don't even think we had car seats at this age. certainly my moms car only had lap belts - and maybe only those in the front seat. that doesn't change the statistics, but we could also drive ourselves nuts with statistics, paint ourselves into a little fear corner so that we never leave the house.
