Both me and my sister are childfree, but things changed when our grandmother got sick and our father looked after her and suddenly she's pregnant. She told my mom that she decided to have a kid because she needs someone to take care of her when she's old.  Anyway, my sis is 300lbs+ and I can almost guarantee my poor niece will be taking care of her up until she can finally move out at 18 and we will probably never see her again. My sister is a total bitch.
