What happened on your DC first day at school, do you introduce yourself to the teacher and leave or is there a bit of a parent day where you get to see what's what and watch for a while?
I ask because every time my DC go into a new 'class' in nursery / daycare (been there since being 1 years old) then DH and I had a 'intro' and got to stay for a couple of hours to settle them in and see how it all worked, meet the staff and ask any questions.
TIA.
