As always, you and your family are in our prayers on your journey.
A note on nurseries. I've never encountered an Orthodox Church with a nursery, but there are probably a few out there. I think that in the Orthodox experience, children should not be barred from the liturgy merely because they are children and may cry. In most parishes, children are with their parents throughout the liturgy, and if a child starts to cry for more than a few seconds, a parent takes the child outside for a few minutes unti the child is calm again. Just as we do not deny the Eucharist to infants, we would not seek to deny them the Liturgy.
