I totally feel as if im not allowed to eat. The second i sit down and take a bite its mom I need this or that. My 3 year old needs chocolate milk. My 9 year old needs help with homework. My 2 month is hungry again or needs another diaper change. It's to much to ask for help but I get told to sit to eat if i do anything else but eat and then i have 3 whiny kids. UGH!!
