Stop it, Malcolm

Malcolm has developed a really annoying habit of playing with my other breast with his free hand whenever he nurses. I have to keep pulling it off or keep my tee down so that his hand cannot get inside. I slap at his hand also but he doesnt care and keep slipping his hand under and inside, yerrrrrrr. It's irritating me a lot and i cant type properly. I tried holding his other hand but he's getting stronger by the day. Haih.... who asked hubby to name him "power" in Chinese.... DOHHHHHHHHH. When's this habit gonna break.
