My baby learned how to growl, lol. Mommy first heard it three days ago when changing your diaper in your room. You just made a growling noise when Mommy was pulling off your pants. I laughed, wondering what noise is that you just made and had not heard it before. You did again after hearing me laughed. Lol, are you learning how to growl because you know it is October, and Halloween is coming up. Maybe you learned it from Mommy because I do a lot of different voices, and sounds to keep you interested and intrigued. Now you growled all the time, even when you are babbling. You babbled and growled at the same time, it is cute to listen to.
