should I be scared?

Samantha • Leila Jade's mommy 👶🏼💘
I keep seeing post about not posting your child's pictures online, I personally think that's crazy bc my daughter is adorable and I want to show her off. Well my sister just started photography and has been taking lots of pictures of my daughter and posted them on Facebook with her full name as the album name... should I have her take them down? She has many friends on Facebook that I don't know... any help ladies? What could go wrong?
