I'm not pregnant but my sister is

My sister found out she was pregnant earlier this year, a week after her 19th birthday. Now her due date is in 3 weeks!! At first I wasn't thrilled because her boyfriend isnt... the smartest or most ambitious person. But the whole family is excited now despite the baby's father. The first grandchild for my mom's side of the family (my dad already has four other grandkids from my step-sisters). I'm just excited to be an aunt!!! 3 weeks or less until baby Mason is here
