What should I bring my host family in Costa Rica?

They live on a small farm. There is a mother who is 38, and we are considering bringing her an apron from Anthropologie, which are about 38 dollars, and very nice. The husband is a driver, and he is 45, I don't know what to bring him. There is an 18 year old boy, and again, I don't know what to bring him. There is a 12 year old girl, should i bring her something like nail polish, or slippers( cute girly ones)? And last, there is an 8 year old girl, and I am thinking to get her something similar to what I get the 12 year old. And last, I am thinking to get them a family gift of linens or towels. My mom lived in a foreign country, and was poor when she was young, so she thinks towels would be nice. It is most likely that the family is very poor, so I will NOT be bringing candy or coffee, or gift baskets, I would like to bring something nice and useful. Also, I'm a girl and 14, if it makes a difference. thank you

I USED TO LIVE THERE...NO COFFEE THEY HAVE PLENTY. NICE CLOTHING WILL BE FINE. IS VERY EXPENSIVE OVER THERE. NICE BOOTS FOR THE 48 YEAR OLD AND HE WILL BE YOUR FRIEND FOREVER . FOR THE 18 YEAR OLD SOME SOCCER STUFF THEY LOVE FOOTBALL SOCCER ( YOU HAVE NO IDEA EVEN WOMENS). TRUST ME I KNOW THEM.
