Drew, not shown here, has outgrown his car seat (not necessarily by a measurement provided by the manufacturer) and is big enough for a booster seat. After our typical shopping around and internet research, we finally found one we liked...and bought two. The most convenient place to do the minimal assembly was the clean, spacious, well lit, kitchen floor (three adjectives that don't apply to too many places).

As soon as Will realized it was a seat that I had pulled out of the box, the following conversation took place:

Will: Sit down?
Daddy: Not yet.
Will: Sit down?
Daddy: Not yet.
Will: Sit down?
Daddy: Not yet.
(Repeat many, many times.)

After a laugh and a quick picture take, I was back at the task at hand, only to be interrupted moments later from the other side: "Sit down?" Yes, finally, Will got to sit down in his brother's new booster seat. Five seconds later, he was off to the next activity. The booster seat was successfully installed and Drew got to get in and out five times today.
