Waving bye bye

Lukas has starting waving bye bye at times. He does not do it all the time, but it is so cute when he does do it. You say "bye bye Lukas" and he will flop his arm up and down a couple times or maybe just once. He will do it at daycare when I drop him off and sometimes at home. It's neat to see him learning that kind of stuff. Next...we need to teach him how to blow a kiss!
