I am struggling to work out what to do next with DD, 2 and 1/4 who suddenly WILL NOT sleep in the day, hates going to old favourite toddler groups without a great deal of persuasion, won't eat old fave foods and will not tidy up. new brother , 4 months old may have something to do with it, but that cannot be undone. what shall I try? Normally she is positive and distractable, lately she is ultra negative about everything and doggely refuses things more. Do I ignore "No" in my face, and how? or do I do naughty steps etc, I am not sure what sort of a pickle we are in but it is tiring. Any ideas welcome.
