Am I right to feel a bit weird about this?

So I haven't been posting a lot of my baby on Facebook very intentionally. (he's 1yo, 14 months, and I've posted him on Facebook maybe twice?)

Last week I sent my dad a video of our son painting.

A few days later my stepmom (who I'm not 100% on one page with because of how she treated me and my siblings) posted the video on her facebook.

I do feel a bit like 😕 about it.. Like I'm intentionally not posting this on Facebook (I did post it on Instagram, because I only have people on there that are actually really close to us, like 8 people or so... I intentionally do not have her on instagram)

I won't be causing drama over it but I do feel a certain way about it like... Idk she could have asked 🤷🏻‍♀️
