My mom gets mad when I give her smart

Answers. She always questions me like I don’t know what I am doing, For my child. Today she asked, with a let-me-dumb-down tone, if I wiped my baby down, especially his hands, before he went to bed. In my head I am just like “mom I am not an idiot.” So I just responded with sarcasm and said “nah, it isn’t that serious to do that.” She got sooo offended and went off on how she’s only looking out for her grandson. And I replied with “looking out for him from whom??!? Your questions are condescending and quite rude, as if I am not a good enough mom for my son.”

Anyway, she annoys me with her stupid questions.
