My daughter just turned 5 this past April, her preschool teacher called me at work to tell me that they believed I needed to get my daughter tested for ADHD. She had a tantrum that day because someone answered a rhyming word before she did. They said it scares the other kids and that a similar scenario happens a couple times a week. They also have trouble with getting her to follow directions, like sit down, stay still and quiet at nap time and to move to another task, she exhibits defiant behavior. My daughter rarely has tantrums at home and we use a visual timer at home. Example, at home we tell her in 5 mins we are going to turn off the TV and you'll get up to brush your teeth before bed. When I explained that's how we are able to get her to do things at home without it becoming a screaming match, I was told they don't have time, they need things done on time. We are consistent with punishments, taking away privileges or leaving whatever fun activity we are doing. We do what we say. I don't know what more I can do at home, there isn't anything I can do about how she behaved at school because I'm not there. Any advice?
