So not sure how this all started...but possibly my love of music is at the core.  Specifically rock music.  Precisely Aerosmith.  Props to sewcuteinaz on etsy for the awesome, constantly commented on Michael Miller guitar car seat cover to bring the craze to my baby.  While I was on Amazon checking out the kids' books mentioned in the previous post I also got some groovy new guitar toys for the little guy.

And found one I'd like!  A guitar spatula by Gama-Go (check out all their products!!  awesomeness!!)  Then check out Fred products- also pretty awesome ;)
