My Little Teaser!

Elton has turned into quite the little tease. He started to say "daddy" very clearly a couple of weeks ago and now when I say "say mommy" he goes "daddy" and laughs hysterically. The more I say "mommy" he says "daddy" and laughs. That is until he wants something or someone and I am the choice. I have even tried tickle torture with him. Dan said that when I was gone this afternoon, that he was upset and wanted something and very clearly said mommy or mama. Do you think the little stinker will say it for me? I have even tried reverse psychology by saying "daddy" to trick him, but he just looks at me like he is smarter than that.
