We have seven grandchildren. Our eldest daughter has three sons, 17, 15, & 13. My middle daughter has one son who is 17. Our youngest daughter has one daughter who is 17. Our son, who was our 3rd child has two children, a daughter 18 & a son who's 6. My husband and I haven't seen these last two children since they were 24 mths & 30 mths respectively.
