Oh boy .. you're not inspiring confidence!!!
My 6 month old (tomorrow!) gets so focused on .. something .. that no matter how many times you call or redirect him, he will go back to it. Drives me nuts. It's even worse right now because we haven't been able to exercise him for the past week and half because of injured (hope that's all it is and nothing more serious) elbow. My son just texted me when he went home to let him out for lunch that he was being a pain in the behind .. both cheeks.
