I bought Davis a Bumbo seat brand new on Ebay for $28 with the tray, I could not pass that deal up even though the seat is purple. He did not want anything to do with the Bumbo until today. He is obsessed with sitting up and almost can on his own but he can't support himself with his hands long enough to enjoy it. Today I decided to stick him in the Bumbo again and he loved it. He kept trying to eat his foot though!
