This girl was about to start her sophomore year of high school, so she was only in 9th grade when she got pregnant! She did seem a lot more mature that most of the kids we see on this show though. When she & her dad were at the restaurant & he told her that Jairo better get it together otherwise he would be holding her back, Izabella agreed with him. So different from most of these girls who don't get it...if a guy has no education & no plans, he's on the fast track to nowhere. Izabella understood that, which is very mature for a girl her age, IMO.
Her dad also made a very valid point when the uncle was saying that Jairo needed to get a job, any job. I thought it was very insightful of her dad to argue the point that if Jairo were to do that & not get his education, then his future would be in minimum wage jobs, but if he gets his education, then his prospects of gainful employment would be better, which would benefit not only Jairo, but Izabella & Enrique. Points to dad for looking at the big picture, not just the moment they were in right then.
