Hi my dd is 20 mo. She is always having tantrums over the most minor things like can't reach something, not alowed something etc. but the problem is she throws herself on the floor and bangs her head, sometimes she does it reasonably gently and watches for a responce others like tonight she does it really hard and makes herself cry more. I have tried telling her no very nicley and explaining why. I have tried telling her off, I have tried completley ignoring it but nothing has worked so far.
Any ideas?
