Pete plays 'Mommy'

My little guy is starting to bite me while nursing. . .fun, fun, fun! (- insert sarcasm here-)
One day, Peter heard me tell James, "No, James, don't bite Mommy".
So, the next day, Peter saw me nursing him, and said to James, "Baby James, don't you bite Mommy. You don't want to hurt her. So, you can NOT bite her. That's not nice. You need to be a good boy. . .like ME!!!"
Who needs parents when you have a smart (but yet, bossy) toddler brother!?!?
