I just came online because I'm so discouraged about my daughter's behavior the last three weeks. When I found this post and replies it helped me feel a little better. My 5 y.o. daughter's behavior is so erratic it scares me. One minute happy, singing, playing and then I say it's time to eat or something, and she freaks out--screaming, kicking, throwing herself on the floor. Consequently, I put her in time out where she yells at us, shouts "I'm angry", if something is in reach she sometimes breaks it. Time outs had worked pretty well until the last few months. We have been investigating Salicylate sensitivity and are ready to try the Feingold diet in case her diet is contributing to the recent changes in her behavior. I also like the push ups idea and will give that a try. Her bad behavior is also at day care--daily, and only occasionally at school. For my daughter I don't think it's related to where she is because she's a sensory seeker, not avoider, and loves going anywhere and everywhere, so she doesn't put in much effort to staying a certain way at school. We do all kinds of physical activities throughout the day, as we always have, but the extreme behavior is very recent. When it comes right down to it she's acting defiant and out of control, which is new to us with her (had it with my son many years ago at age 14-16). I feel like I've hit a brick wall. We've tried everything to help her, and it all seems so fruitless sometimes. I hate SPD!!!
