I stupidly shared an IG video of my LO standing on her rocking horse. It was the very first and (so far) last time she's ever done it. MIL said:

"OMG... You must keep it so that she can only use if when you are watching. She is too young to do things like that on her own."

I wasn't offended when I first read it and just laughed it off, but the more I think up a response, the more it erks me. WTF, she's a baby. She's never, ever unsupervised.

How should I respond? My normal reaction is usually a little lighthearted. But I don't want her to actually think we leave her unsupervised.

Edit: to clarify, I didn't intend to take a video of her standing on her rocking horse. I was trying to take a video of her rocking on it, but she went daredevil on me
