We have one today but couldn't get a babysitter so we have to take our 3 yo and 5 yo with us. I'm not sure it's appropriate and I'm kind of dreading it. Have you ever had to do that before?
EDIT: Thanks to some earlier replies I sent the teacher an email and she said if I thought him and his brother could play together quietly they could come. And so they went. LOL! It was cute because afterwards he came up behind me and whispered in my ear "How'd I do?". I didn't even know he realized what we were doing. He was happy to find out he's doing great!
Thanks for ALL your replies. I've loved seeing your responses. =)
