To breed villagers in Minecraft, follow these key steps:

• Provide Beds: You need at least one bed per villager plus an extra bed for each baby villager you want to produce. For example, if you have two adult villagers, you need at least three beds in the breeding area. Beds must have at least two blocks of vertical space above them for villagers to claim them properly

• Give Food: Villagers need to have enough food in their inventory to become willing to breed. You can throw food near them for them to pick up. The required amounts per villager are:
  • 3 bread, or
  • 12 carrots, or
  • 12 potatoes, or
  • 12 beetroots. Villagers will share food with each other to reach the required amount, increasing their willingness to breed

• Isolate Villagers: Place two or more villagers in a confined space with the beds and food. They must be close to each other to breed

• Breeding Conditions: Villagers breed only when they have enough food, there are enough beds, and they are willing. You might see hearts appear above them indicating breeding mode. After breeding, a baby villager will spawn

• Additional Tips:
  • Villagers breed after their workday or during village meetings.
  • Making new trades with villagers can increase their willingness to breed.
  • The number of villagers in a village is limited by the number of beds available.
  • Villagers automatically harvest crops in gardens, which can help supply food for breeding

In summary, to breed villagers, ensure you have enough beds, supply them with sufficient food by dropping it nearby, and keep two or more villagers together in a well-lit area. When conditions are met, villagers will breed and produce baby villagers
