Can anyone correct this?

DESCRIBING MY FAMILY
I’m forty one years old. I’m the youngest child of five. I have two brothers and two sisters.
I get along on the best with my the oldest sister, María, because she has been like a second mother to me. When I was a child, she watched looked after me, because my parents worked all the day, and I hardly ever saw them. My sister, also helped me with my homeworks. Now, she has two children: one son and one daughter. My nephew is very clever, but he’s a bit disorganized too. My niece is really charming and very sociable.
The second member of my family is Pedro. He has one daughter and two sons. He is a hard-worker, so he spends a little time with his wife at home. He´s always travelling because his job. These nephews and niece His children are quite funnyies. They are always making jokes.
The My next brother, Carlos, is the most generous person in the family. If you have a problem, he’ll help you as soon as he can. On the other hand, he is a bit stubborn and he always thinks that everything he says is true all he tells is true, and other people are wrong. He has two daughters. I am the godfather of one of them. Both are very intelligent and friendly.
The fourth member of my family is my sister Eva. She is very responsible and kind, but when she was a younger girl she was a bit spoiledt. She and I usually played together many years ago. Now, she has two daughters, and I am the godfather of one of them, too.
Finally, I have two wonderful sons. They and my goddaughters are very dear to me my darling.

It sounds like you have a very nice family.:)  One thing to note is that when you hear an English speaker say cause instead of because that it is us being lazy.;)  To write it out correctly it should be because. Have a great day.

Good job.  Many English speakers use 'cause' instead of 'because' for slang.  It is not correct and since you are learning English I would always use because.

The other correction has items marked as wrong that are not wrong :(
