. . . . from a car seat to a booster seat. Trust me when I say he is not happy about it. Nikolas is a backseat driver, he has to be able to see out the window, which he could do in his car seat. Unfortunately, in the booster seat he can't see out the window that well. So I tried to help him out and made him this little pillow to sit on. I used a towel because it would be durable for all the messes little boys can make.
