Comment made about my 3 month old’s head

I’m worried after a comment was made about my LO’s head size that something is wrong. My husband’s mom asked if the pediatrician had mentioned something to us about it being large but he’s always been given a clean bill of health at his visits. She wasn’t hateful or anything, but it hurt my feelings and now I’m worried that something is wrong with him. He is in the 97th percentile for his head circumference and did give me a 3rd degree tear, but there’s never been any mention of hydrocephalus or any other issues. I’m trying not to spiral! Ugh
