My four year old daughter very likely has ADHD. I'm not diagnosing her, of course, but all the signs are there. It's in the family (myself, mom, grandma), she is very verbal, but has the attention span of a gnat, she's all over the place and has trouble being still. At home, it's not an issue, really. She gets in trouble occasionally, and she's a bit of a smart mouth, but it'd doable, especially if we stay on her schedule. She started preschool this year and has had some behavioral issues, mainly things like getting in other kids' business, not paying attention during circle time, running when she's not supposed to, etc. It's something almost every day. She also has trouble working independently. I'm considering taking her in to get a diagnosis and see if they will start medication. She is already telling me that she's bad in school, and I really don't want to start a negative association to school this early. I know most people want to wait to medicate until 6 or 7, but by that point she could already hate school and be labeled as a bad kid. Her teacher this year is wonderful and very patient with her. She makes sure to always tell me daughter she likes her and every day is a new day. I just hate to see her continuously get in trouble for something she (may not) be able to help.
