Maxwell Drew Johnson is one impressive little girl!
At least that's what Mama Jessica Simpson says!
Maxwell can whistle on cue at 9 months! Heck I'm still learning! This lil human impresses me everyday.

Really? Wow, that is impressive! We couldn't whistle until we got our two front teeth!
We wonder if she's going to be a singer like Mommy!
