My 2.75 yo DD is being incredibly challenging at the moment. Won't listen to anything I say and seems to be regressing to babyhood. She's been toilet trained for a while and is now refusing to tell us she needs the loo. She's also incredibly clingy, loud and whiny. I'm 34 weeks pregnant, knackered and increasingly short tempered. Please help me find a grip and a way to deal with her that doesn't end with me shouting!
