I am starting to think my 3 year olds awful behavior is more than just typical threenager stuff. Sometimes she is awesome and sweet and listens....but then there are the other times where she is a nightmare. Literally, screaming, demanding, spitting, gagging, hitting. It's insane. My husband, my parents, everyone is at a loss as to what causes her to act this way and we have no idea how to get it to stop. We can all be giving her attention, or doing something fun, or she can be bored and not doing anything at all...there really is no pattern. It can be when she doesn't eat enough or when she has had plenty to eat. I could really use some advice, she's like a kid you would see on Nanny 911...I'm stumped.
