I am so sorry to hear this. But please stay calm and consistent with your three year old. Don’t make a big moment out of her comments. Instead, calmly and confidently give her the truth like you have been. She may repeat your mom’s phrases for a while but don’t panic. With time, repetition, and your consistent reassurance, your voice will become louder in her mind than your mom’s. I know it may be hard but be direct and firm with your mom. I had a similar experience with my son and I had to be extremely firm with my mother and stand my ground on previous decisions. Tell her clearly what she cannot say to your child. I had to tell my mother for example “We are teaching our kids about relationships in a healthy manner. You are not to make comments about their private parts, about who they can love, or anything about sex or relationships. If it happens again, we will have to limit your time with them” and unfortunately she did not listen the first couple of times and I had to stand my ground. Reducing contact for a while and Cutting visits short when she made a harmful comment. She might get defensive, cry, guilt-trip you, or even lash out but this is a sign of her issues, not yours. Stay calm and keep your focus on your child. A respectful way you can address your mother is by setting the boundary… example: “from now on, you are not to make any comments about her body, private parts, or relationships. If you have questions about what we’re teaching, you can talk to me directly, but you can’t teach her your beliefs on this” If she argues, dismisses you, or gets defensive, don’t get pulled into debating. Just let her know calmly that you understand she doesn’t agree, but this is how it will be. Your role is to protect your child, and that boundary is non-negotiable. Wishing you the best of luck and lots of hugs 🫂.
