Exactly what I was going to say

Having trouble with socks isn't trivial when you are a toddler!
She wasn't even having trouble with her socks when she started crying. They were just inside out, which is how she wears them half the time with no problems. Then suddenly it was a problem this one time.

I do always remind myself that she still has a lot to learn still and that things are harder for her. But everything changes from moment to moment. One moment she wants a banana, next moment she doesn't. One moment her socks are fine, next moment they're not. And her reaction is to cry. I just feel like then I can't do anything right in those moments.
