Getting bashed for posting my baby online

I post my baby on my story probably twice a week since she’s been home (she’s 3.3 months). I only have 100 followers combined on my pages but my pages are public. I’ve heard that I’m exploiting my child. However, I’m not trying to get anything out of it. I have 0 friend in real life and barely family so since I have no one to send my babies pics to I post online. I want to keep posting my baby but I’m not understanding why I’m being bashed on the internet by random strangers.
