<human>: My wife, Shawna [25/F] and I have been married for 7 months, but we dated for 6 years before that. Her sister Selena [23/F], doesn't often shower. Sometimes she will go several weeks without showering, only washing her hair when someone complains about it. 

My wife and I have recently had a baby girl, Rebecca. She is 3 months old,  and our first born.  Everyone loves to hold her and she loves the attention, but we have started having issues with her Aunt. 

Selena has never showered regularly, going weeks between showers despite Work, School, and Boyfriends. We have attempted to talk to her about this before but she has never listened to us, always acting like we're joking.  It has recently become a health issue, with just two weeks ago, her having to had surgery to fix where hairs on her lower back had gotten so ingrown, and gotten infected from the dirt on her. 

She smells bad enough that you can smell when she's been in a room hours after she has left.  When she holds Rebecca, we actually thought she had soiled her diaper she smelled so badly. The worst part is, Rebecca will smell like Selena for hours after she is held, to the point that we scrub our daughter down after each time Selena holds her. 

Because she wouldn't shower often, I put my foot down and told her that unless she started showering she was not allowed to hold our daughter. My wife agrees with me, as does her other sister, Scarlett [23/F], who has a 6 month old daughter, Ariel. However,  when we walk out of a room we will always find that Selena ignored us and picked her up, or someone handed her off. It's making the entire family tense and I'm not sure if I want to start an argument over this.

Can you provide a brief overview of the text?
<bot>: Sister in law doesn't shower, holds baby and makes her stink. Told her she can't hold our baby until she starts showering, but she doesn't listen and it's causing family drama.
