HFM, how horrible was it for your LO?

My 4 week old and my 1 year old. Boom. Ironically enough my newborn never got a fever although he got the rash and loss of appetite. My 1 year old however is HORRIBLE. it's bad. He had covid and an ear infection and I think HFM is far worse. Holy hell. So, what helped your LO's and also how long were they miserable for? Anecdotally of course. I just want to know hoe long we will be in the depths of hell for. Bc we are on day 3 and im...omfg over it. So over it.
