Anna and Ben are twins. They like to play with their toys and run around the house. But sometimes they get tired and need a nap.
One day, they were playing with their blocks and trying to build a tower. They wanted to see how tall they could make it. They used a measure to see how many blocks they had. They had a lot of blocks, but they wanted more.
They saw a big box in the corner. It had more blocks inside. They ran to the box and opened it. They took out the blocks and added them to their tower. They were very happy.
But the box was heavy and they had to lift it. They lifted it too fast and they felt dizzy. They dropped the box and fell down. They felt sick and sleepy.
Mommy heard the noise and came to see what happened. She saw the twins on the floor and the blocks everywhere. She was not angry, but worried. She picked them up and hugged them. She said they needed a nap.
She took them to their bed and tucked them in. She gave them a kiss and a teddy bear. She said they would feel better after a nap. She turned off the light and closed the door.
Anna and Ben closed their eyes and snuggled with their teddy bears. They forgot about the blocks and the tower. They dreamed of happy things. They had a good nap.
