Hi My DS (2yo) is not coping too well at the moment with arrival of new baby (3 months). Worst time is when feeding . Have no idea what I can do to discipline him when am busy feeding the baby so can't start the naughty step etc as can't keep stopping feeding every 2 seconds to put him back on it. I feel this it the time when he is his naughtiest and I am most helpless - please any tips!!!!!
