My FIL died before a year. My MIL lives with us. My daughter is now 2.5 years old. My MIL treats my daughter like her child. She is telling to my daughter that she is her bigger mom and I am her little mom. We planned to bring her in a good mannered child but she spoils his mannerism. Simply to tell, she not putting panties just roaming with her dress alone. when i ask her to put, my mil is against me. My hubby too talked to her, but she is very much stubborn and saying that she knows well about parenting than you or your wife. What should I do?
