Firstly, of all the HP couples, I love Molly and Arthur the best. They are obviously deeply in love, have worked diligently to raise their children to be good people and are amazingly adorable in general (Mollywobbles! Swoon!)
But, in general, Wizarding families seem to be light on the children front- some sort of BC potion or charm I would assume. Religion seems to be pretty scarce also- but are we supposed to believe the Weasley’s are Wizard Catholics? Do they have a moral/religious objection to BC, or are they just people who like children a lot? Because the sheer number of Weasley’s is enough to be remarked on by nearly everyone.
