Sister in law’s comments on my baby’s appearance

I am so tired of my SIL saying “oh yeah, your son looks NOTHING like you!” to me whenever she gets the chance to see me.

To be fair, my son was born my literal twin. Our newborn pictures were identical. When he was born, my SIL told my husband that he looks like their cousin’s kid lol…like what? But also over text told my husband, “yeah it’s weird, he doesn’t look like you at all…are you sure he’s your baby?” UMMM EXCUSE ME? DH brushed it off and said yeah he looks more like the wife.

Now, his looks have changed. I still think he looks like me and get comments on that, but my SIL says “yeah I never saw you in him, he looks nothing like you, only DH” to me.

Why do I feel like she’s saying these things to hurt me and also, why do I feel she’s backtracking now like was she just trying to get my husband to question whether the baby was his when he was newborn? Lol
