Minecraft Villager multiply?

How does Mann Villager multiply? Already have two farmers. I want to couple and build a village

Do not know that by heart right now, but have a look here

If you give them food

For two villagers to father a villager child, both must be in a pairing mood and there must be at least one unused bed in the village.

Give everyone three loaves of bread. They also need at least three beds, over which, as far as I know, there must be at least two blocks.
