[My correction]

 

若い子供が公園で遊んでいます。
→小さい子供が公園で遊んでいます。
A small child is playing in the park.

 

小さい is used to describe someone of a young age whose body is not yet adult-sized.

小さい describes young individuals who haven’t reached adult size, while 若い refers to young adults with adult-sized bodies but are still considered young in mind. 若い is not used for babies, infants, or very young children.

 

Examples:

結婚(けっこん)するにはまだ若いです。
I am still young enough to get married.

 

むすこはまだ小さいですよ。
My son is still a small child.
