What would you do if a family member ou would always tell you what to do and judge you?

My boyfriend sister-in-law loves to judge and tell people what to do. I call her a golddigger because she's all about the money. She don't have a job, but she always gets money from her hubbyer or her mom. She spends it on things she don't even need and she bought a whole lot of stuff for her almost 2 year old daughter. Anyways, She's always judging me and telling me what to do with my son. He's almost 2 as well and still have a pacifier, but it's my choice how to get rid of it not hers. She says that he's gonna get buck teeth or something like that, but I don't know. If someone gets a new pair of shoes or something she always ask how much were those or were did you get them. She says that she always helps the family out, but really her hubby does because he has the money. My boyfriend mom has owned them some money, and she always got on her about it when it wasn't even her business. UGH! Does anybody else have one of those?
