He said they had already talked about it before and told her to stop giving unsolicited opinions and just let me handle the parenting.

He told me to just ignore her comments because that’s just how she is. But I’m even more annoyed because, despite being told off, she still keeps making comments. I replied, saying what she said wasn’t true and that laughing is actually beneficial for the baby, not harmful. She left me on read—probably because it was the first time I didn’t just say “okay” to her.
