So am I wrong for thinking this comment is quite rude? And getting angry over it?? 
My daughter is 2 years old and when we are at home (in warm weather) she prefers so be only in a diaper so I let her... 
Also, I only have 25 people on my Facebook and they are only family and a few very close friends whom are parents themselves. 
This person is my daughters aunt on her dads side. And I am even more upset since they don't contribute to or help out with anything. Yet can say this? If she wants to sexualize my daughters body then that is her problem! She is a baby for goodness sake!!!
