Okay kiddo, so imagine you have a big toy box full of toys. Now, you decide that you want to separate certain toys from others and put them all in different piles. That's kind of what happened in Cuba after the revolution.
The revolution was like the grown-ups in charge deciding they wanted to change things up, so they got rid of the old way of doing things and started a new one. They wanted everyone to have good things like food, healthcare, and education. They even took away things from rich people so that everyone could have a fair shot at life.
But now that they had done that, they had to make sure it all worked properly. Just like after you organize your toys, you have to make sure they stay that way and don't get mixed up again.
So the Cuban leaders had to make sure that people had enough food, that everyone was going to school and could read and write, and that everyone had access to a doctor when they needed it. They also wanted to make sure that no one wanted to go back to the old way of doing things.
They worked hard to make sure that everyone had access to the things they needed, even if it meant leaving behind some of the things they used to have. They also made sure that everyone knew what was going on and that they could have a say in how things were done.
In the end, this is what we call the consolidation of the Cuban Revolution. It means that the grown-ups in charge made sure that all the changes they made were working properly and that everyone was happy with them.
