parent teacher conference

what do you usually ask at a parent teacher conference? my son is 10 months old. my comcern is how is her speech development doing as I know teachers are not always there to talk to the kids at IFC. my son is our first child and not sure what to expect for milestone. milestone says suppose to able to say some syllables but we not sure if he is actually doing it or we are just imagining it. what else should I be asking pertaining to development?
