to come to the toddler playgroup

Girls, I have to go to the toddler playgroup this coming Friday for a meeting about my son. He's 2.5 years old and has been at the playgroup for 4 weeks now. The teacher says he doesn't listen and has no concentration. He's also causing disruptions in the group.

She also mentioned that he has a very spontaneous character and that I shouldn't make a big deal out of it. But she wants to have a chat to see if he's like this at home too, and she wants to give me some tips.

In my opinion, he's just a busy, enthusiastic toddler, and I didn't see this coming! Does anyone else have experience with this? Thanks,
