DN (2yo) was over recently, playing with DS (also 2) and they decided to play hide and seek. I could see DN and DS hiding behind the curtains and their feet were sticking out the bottom. It looked very cute so I snapped a photo and uploaded it to FB with a caption along the lines of having two little intruders in the house.
However SIL later saw this and sent me a long message about how she wants tone private and doesn't want any photos of DN on social media and how could I do such a thing etc etc. I took the photo down immediately of course, but given that all that could be seen of DS and DN was their feet, was she being a bit unreasonable in her response?
