Could you check these two paragraphs for me, please?

Thank you
1) Many years ago, when my uncle was only six years old, while he was playing on the balcony, which was on the second floor, one of his toys fell down and crashed on the ground. He wanted it back so he decided to climb on the small wall which stopped him from falling but in the end he decided to jump down. My grandmother arrived and saw my uncle on the ground. She screamed and jumped into the car to take him to the hospital, but he was fine. Fortunately he only had a little scratch on his right hand.
2) Last year I went to my cousin’s house for a few days. One afternoon when we were in the garden, while she was eating a strawberry ice-cream a big bee bit her tongue. She started shouting and I saw her tongue become enormous. The unlucky girl immediately went to the hospital to talk through about the event with the doctor. (to let the doctor see what happened) At the end she couldn’t eat solid food for one week. Every time I think of this story I start laughing and she falls out with me every time.

1. Very wordy; rephrase with fewer words (less repetition):

Many years ago, when my uncle was only six years old, he was playing on the second-floor balcony and one of his toys fell down to the ground.

Comma uses, again and again and again ...

2. More wordiness!

One afternoon, when we were in the garden, she was eating strawberry ice-cream when a big bee bit her tongue.

... I saw her tongue swell up.

... to the hospital and told the doctor what happened.

... and she becomes angry with me every time.

You have a tendency to use too many words. After you have written something, read it outloud. If there is repetition, see if you can find a way to be more to the point.

1) Many years ago, when my uncle was only six years old, while he was playing on the balcony, which was on the second floor, one of his toys fell down and crashed on the ground. Long ago, when my uncle was only six, while he was playing on a second floor balcony, one of his toys fell to the ground. He wanted it back ; so he decided to climb the small wall to jump down. When my grandmother saw my uncle on the ground, she screamed and jumped into the car and took him to the hospital. Fortunately he only had a little scratch on his right hand.

They immediately took her to the hospital and told the doctor what had happened.

falls out? she gets angry with me.

Sure, I'd be happy to check those paragraphs for you. Here's the corrected version:

1) Many years ago, when my uncle was only six years old, he was playing on the second-floor balcony when one of his toys fell down and crashed on the ground. He wanted to retrieve it, so he initially considered climbing over the small wall that acted as a barricade to prevent falls. However, he ultimately decided to jump down instead. Upon witnessing his landing, my grandmother was alarmed and quickly rushed to the scene. She screamed and immediately got into the car to take him to the hospital. Fortunately, he turned out to be fine with just a minor scratch on his right hand.

2) Last year, I visited my cousin's house for a few days. One afternoon, while we were in the garden, my cousin was enjoying a strawberry ice-cream when a large bee stung her tongue. Due to the impact of the sting, her tongue started to swell significantly, causing her to shout in pain. Concerned by the situation, she hurriedly went to the hospital to consult with a doctor and showed them what had happened. As a result of the ordeal, she couldn't eat solid food for a week. Whenever I recall this incident, it always brings laughter to me, although my cousin tends to get upset with me each time.
