Help - my DD who is usually so happy, smiley, gentle, laughy has suddenly (in the last 2-3weeks) changed and become another child. She says "no" or "i don't like it" or crys and screams, arches her back or throws herself on the ground when asked to do anything she doesn't want to, particularly getting dressed, putting shoes and socks on, going out, going downstairs to bed (actually ok once shes in), taking a bath, cutting nails or just whenever she is being taken away from anything that she is enjoying (which obviously sometimes has to happen). I try to pick my battles and usually end up getting the result in the end but it has become so difficult and takes so long to do anything and I am not totally sure how best to handle the tantrums. I don't raise my voice and I don't want to be a mummy who shouts and sticks her on a naughty step all the time - any suggestions of how to deal with this is a firm and loving way???
