Mom, I think I've outgrown my car seat!

I think James has outgrown his infant car seat, and just in time for his six month birthday!  The specs say up to 30 inches or 30 pounds, and I think he's around 27 inches and 18 pounds, but he's kicking the seat and his shoulders are pretty darn squished, so I say it's time for a new car seat.  Maybe Dad will install his new one in my car this weekend?
