Alex - already minding mommy?

I have to document this...

For the first time yesterday I think Alex actually listened and understood what I was saying. When Alex crawls over to the fireplace he likes to stand up and bang on the screen - I always say "NO", but he usually just looks back at me with a devilish grin and does it anyway. However, yesterday he stopped just short of the screen, sat up and starting throwing his arms up and screaming in discontent, but at least he didn't touch it. I think he finally is understanding what NO means! We will keep practicing though - I am sure I have many more battles ahead!
