I have a baby girl who has just turned one year old ,I have been in a relationship for three years now with my partner, i have another child who is seven with my ex , he sees his son three days a week he has a new partner well when I say new they have been together for about 10 months now she does seem very nice to my son and my ex seems happy and I didn’t have a problem with her UNTIL she came to my house with my ex a few times and has made comments about my baby girl and how small she is my daughter has been to health visitor and doctor now because of these comments and they told me she is perfect height and weight and she is doing really well , every time I see his ex and she makes this comment I want to punch her in the face I know I’m over reacting but she made me paranoid that there was something wrong with my child , should I say something or just keep quiet my partner says I shouldn’t say anything cause it will just cause an argument but he doesn’t like confrontation where as usually if I want to say something I will any advice on if I should and what I should say to them 🙄
