Question about how to handle unwanted advice or judgement from family members in regards to how I raise my children.

So a little backstory for context:

I am working on and fully believe in natural consequences if and when possible, to help my kids learn on their own the consequences of certain actions.

For instance, I tell my daughter everyday, weather is getting colder, please put something warm on. She came out in a tank top and jeans this morning.. so I made sure she had a heavy wool lined sweater with her. And the daycare provider (also my aunt) took and sent a picture of my daughter INSIDE without her jacket on (let me emphasize she was in a heated school) and forwarded it to my grandmother. Who then forwarded it to me and my husband ”Hey guys there are two jackets here. Probably Gracie's. Does she or Lu need? Tasha sent me a picture of Lucie with the sweetest smile 😍and very lightweight summer tank. So hoping they jacket here is not hers.” I took offense as too being questioned on if I would send my child to freeze at school without a coat and a tank top… these two women, my aunt and my grandmother always have something to say about how I parent. I do not feel as if I am in the wrong for allowing her to learn on her own what wearing a tank top in this weather after being told to dress warm, and making SURE she has a warm coat.. and I don’t appreciate my aunt taking pictures and sending them to my grandmother and them probably gossiping about how she’s dressed.. I don’t know how to handle this going forward. But I’m upset and want to draw the line.
