I seriously have had this exact same high chair since Natasha was a baby. We got it in Pittsburgh from an add out of the Penny Saver. Tamsyn and Trey used it in Singapore and then it made its way to Washington.
Four babies and I don't know how many meals -- but Dantley is the first to do this!
I cannot turn my back on him when he is in that thing. He thinks it is a stage or something. We have caught him several times up there like he is surfing a killer wave. Instead of putting him in there with a few cheerios to snack on while I make dinner I have to let him roam free underfoot.
He climbs out of the belts in shopping carts too! I am just glad he hasn't figured out how to escape from his car seat quite yet.
