Hello Suenos096! To answer one of your questions, no a 14 y/o is not considered a child. At 14 they're old enough to work a job.
Also, let me caution you about getting too many villagers till you are at level 2 (and better yet level 3) farming. So many tribes have been "lost" because they outgrew their food source

Also, let me welcome you to the forums, and encourage you to go to the introductions section and post an intro. That way all your new friends here can greet you in style
