Mother in law makes me uncomfortable when...

Jessica

She changes a diaper on my daughter and when her diaper is off she blows on her private parts to dry her? But she laughs about how my daughter thinks it feels great and she’s not TRYING to be weird or creepy but it makes me SO uncomfortable. Am I wrong for feeling off about it? Also she would never do anything actually gross to my daughter, I’m not worried about her doing anything bad by any means it’s just one of those weird things she does that drives me crazy.
