Kbug started waving bye-bye a couple weeks ago, and he does it the right way. Dylan and most other babies that I have seen wave bye bye close their hand inward towards themselves, but KBug closes his hand outward and waves his hand/arm up and down. It is so cute. Whenever we talk about leaving he smiles and starts to wave BYE- BYE! Usually when Mommy is leaving and waves bye bye KBug will wave with his big ol'smile and its like a light goes off and he realizes Mommy is leaving so he dive bombs towards me. He is still quiet the mama's boy.
