Is it wrong?

Is it wrong for me to get annoyed when my MIL constantly talks about how my daughter looks like her dad? Like she brings it up every time I post a picture or we talk. She even went on to say that my daughter looks like her?! Sometimes I feel guilty getting upset but I’ve talked about how it hurts my feelings and she consistently does it still. And the thing is that if anything she’s an even mix of the two of us. Maybe I’m just hormonal...idk
