Hi Katchie, it sounds like a good idea to give yourself a break. As you know, we preach hardcore self-care here at SR.
I'm not a Mum just a teacher/auntie so please ignore the following if it is inappropriate .
With kids, I have found the more I fret and worry about them the less they feel they need to. The more I present a kind of, "Ah well, you are smart and can figure it out . . . and by the way . . . change subject to something else . . ." the more it makes a vacuum in the worrier role of the situation.
That being said, I don't know if I would be doing as well as you are in this scenario . . . . even if you are lying on the floor drumming your feet and screaming.
Big hug and keep posting.
