I am a divorced mother of two children - son age 12 and daughter age 14. They are no saints, believe me. I am the first to admit they are spoiled and can be very hard to deal with. However, my bigger problem is my fiance has two children much younger - two girls ages 6 and 9. The 6 year old is his biological daughter, but the 9 year old is adopted. It is his ex wife's sister's child and they adopted her at age 3 months. My fiance has shared joint custody of these girls.
