because I told her to listen to me when it comes to my son. if I tell her to do something regarding him i.e putting him down on his mat so he can sleep (we wasn't at home) and get comfy. he likes to roll over onto his belly and sleep that way and if he can't roll over he screams. she went well he's comfy on his pillows (meaning her chest). I replied well do whatever you want looks like it's the total opposite to what his mum wants and knows about him. to which she turned education round and said just shut up you bitch....
DP wasn't there to hear it as he had to pop out to get something for ds. when he got back I tried to tell him but she kept talking over me to hide what she said.
