PP are you in the primary class or 2s program? I haven't had the same experience (re: school events) but perhaps the room parents in our class are not as active.
I've had some issues with lack of coordination/ communication between main teacher and afterschool teacher, but I guess we will figure it out.
Do you think both parents attend the social night? I don't know that we will get a sitter for both of us to attend (maybe one will attend, and then the other).
