Peanut, Peanut!!!!!!!! I forgot one thing!!!!
I know I told you to hiss, hiss, hiss at your brother, and that works, but I forgot the most important things.........
1. Get in your mom's lap and stay there! :)
2. When "he" walks near to you, start a very low pitched growl, and do it over and over. You'll probably scare your mom, but she'll be ok. ;) If you do it loud enough for that boy to hear, he'll probably turn around and back up some. That's what my brother did this morning!!! :p
Good luck!
Love,
Mimi
