I am feeling really desperate about 10 mo DD. She is utterly charming in many ways. She is also a little madam. She has perfected an angry yell of ear-shattering volume, and she uses it often... I cannot leave the room at home without her screaming, and she won't sit in a high-chair, car seat or pushchair. I look with envy at those people who can just bung their children in the pushchair and take off to the park - this results in a tantrum from DD. It just feels so utterly exhausting and draining. Sleeping is also rubbish at present, which I am pretty sure is teeth, but is contributing to me feeling really hopeless...
What, if anything, can I do to try to teach her that angry screaming doesn't get results (because it usually does...)?
