I am so fortunate that in a Novus Ordo Mass our priest follows exactly what you have taught your daughter -- we remain kneeling until everything is cleared off the altar and the priest is seated. THEN -- we can sit down!
When I brought this to the attention of a Extraordinary Minister of Holy Communion (because the priest was at the other door shaking hands) I got a "so what's the big deal" look.
It's nice that your parish church still has kneelers. I trust your pastor doesn't allow Dan Schutte's music ("Here I am Lord" etc.) because of the implicit humanistic and homosexual agenda in those songs as published by the Oregon "Catholic" Press.
