Is my SIL exploiting her kids?

I'm trying hard not to judge my SIL. She's a good mom and does what she needs to do for the betterment of her children. BUT...she is very open about the struggles with her youngest son's autism and her middle son's food allergies. She posts pictures on social media (just her private Instagram, she doesn't share this on FB) of her autistic son's meltdowns, captioning the photo 'this is autism' and some lengthy explanation and silver linings of raising an autistic child. She posts photos of her son sobbing his eyes out, with pricks in his back, clearly in pain, after being poked numerous times for allergy tests (he had a recent random reaction ) and captions it 'this is food allergies' and adds a lengthy explanation lecturing about food allergies. I am so upset by these pictures of these children in pain. I feel like she's exploiting them. I don't feel like it's to raise awareness, I feel like it's a way to bring pity and attention to her. I can't fathom taking pictures of my children in these moments, it's just so wrong to me. I don't want to get involved, I will unfollow her if I have to, but is it something I should bring up to her?
