Our friends Hayden and Melissa let us borrow their Bumbo seat. It works on trunk strength and head support. It is also something that Luke LOVES. He sat in it for 30 minutes and watched the Lakers and Celtics play. The following night he sat in it for over 40 minutes and played with the gadgets while wobbling his head around. I enjoyed having my hands free for a bit so I could snap some pictures. I got a kick out of the fact that his shirt says "handsome" with a trail of drool running down down to his belly button. Thanks for the loan. The seat is amazing! He absolutely loves it!
