Mother in law trouble

I don't like talking about ppl but I'm so fucking done !! My boyfriends mom keeps talking shyt about me and my 7 year old daughter and that she feels bad for my 1 month old son. She says that I dress my daughter bad cuz I put leggings on her but when I do is under a dress or skirt or a really long shirt (u can't even see her butt or nothing) and I'm a bad mom no, I stay with a job , a house and always have food and clothes, shoes for my kids. My daughter gets good grades in school and she's respectful ( she does have a smart mouth sometimes) and I my boyfriends mom the job she got now so I don't know why she keep talking about me. I have never disrespected her at all this shyt just getting old. Sorry about that but I needed to vent.
