A lady at Costco told me my son was annoying! What would you do?

I was feeding my 18 mo old son with my 9 yr old and she came up to me and said “do you let him scream like that at home?” I said why? She replied “because it’s annoying” He was doing a happy squeal because he was eating. I know it can be very high pitched and I’ve tried to get him to stop by saying “no” firmly and I make him say “please” before every bite. This really upset me!!

I proceeded to have a conversation with her, but I want to know what you ladies would of said if someone rudely came up to you while you we feeding your kids. It’s not like it was at a nice place.. it was Costco!!
