My two year old is driving me nuts. She has always laughed at me when I tell her no and now that the newborn is here it is so much worse. She does things on purpose to get me to come get here. We do time out for things that are dangerous (jumping on the couch, dancing on the coffe table, etc) and she loves it. She asks for time out. Yesterday after time out, she made a beeline back for the coffee table and climbed on it then climbed down and put herself in time out and laughed about it. Same thing this morning, she laughed the whole time. I use my sternest voice and get on her level but she laughs at me the whole time. It sends my blood pressure through the roof because I can't feed the baby while my toddle is climbing everything possible. What can I do?
