What am I doing wrong when growing villagers?

In Minecraft I built a Villager breeding two days ago, as shown in the picture below. As far as I know there should be more doors and beds than Villager and you have to drop them food. It worked for the time being, but I just tried it, and angry Villager particles appeared instead of a child. What does that mean or what did I do wrong?

If I have it right in my head, there are still wooden blocks over the doors.

No

In which version are you playing 1.13?

It's just my last stand. I haven't played it in ages.

Maybe they can't get up on the beds, but actually there aren't that many.

Build houses for them, then they will feel more comfortable.

You can remove the doors, they no longer need them.

You have to set up the beds so that they can get to them and sleep.

These are farmers who need space to grow things, so farmland. If they can, then farm them and mate independently without your help, provided free beds are available for the children. So put up more beds than Villager.

If the farmers no longer harvest the fields then their inventories are full, then they can't mate, then you have to harvest the fields so that the villagers can replant them.

You stacked the beds, which is why the villagers can't get there, why the beds don't count. They have to be reachable.

You can leave out doors that are no longer needed.
They need food (bread, wheat, carrots or potatoes). I think to pair once each have to have 12 pieces of one.
When the storm clouds come, it means that there are not enough beds.

I always make a room where the floor is made up entirely of beds. It always goes well.
