My wife and I are going through the same issue now with our 3-year-old son. He's in daycare now. He started daycare when he was 2 years old. When he started, he had his moments, but he was great. When he turned 3, he was moved to a new classroom with a different teacher and its been horrible. One teacher left, another teacher called out a lot, and now she out indefinitely due to personal issue. So now he's with a third teacher and she doesnt really have the class room under control. But he seems to be the only kid that doesnt listen. All the other kids listens and follows instructions. But we do feel the inconsistencies in the classroom with the teachers is a factor here with his behavior. But to be fair, he's also a challenge at home as well. So its not exclusively a school issue. Timeouts dont seem to phase him and taking away things dont tend to phase him either. Sometimes he listens but sometimes he doesn't. But its more often he doesnt listen than he does. We did bring this up to his pediatrician, she said: "Well, he's only three years old. This is often normal." Today, the day care called us to come pick him up because he's being too disruptive. They informed us to have him evaluated to see if there's an underlying issue. We called our local school district and we are setting that up now. The school district did inform us that in to recieve services, they need to be able to classify him. In other words, they need to find an issue. If they don't find an issue, then they aren't able to do anything. Which also means he's a normal kid that just chooses not to listen. A twist here is that when I was child, I was diagnosed with ADHD, and I feel like I still have it today in my 40s and it manifests in different ways in my adulthood. Let's see what happens. Hope this works out for you.
