What does Long Covid in children look like?

Every time one of my kids (~5 and ~8) has something weird going on I start worrying that they might actually have Long Covid and not able to describe the issues well enough for us to catch it.

As an adult with years of experience about what's normal for myself, it took me almost 3 years to realize I had LC. For a kid who is still getting used to their own body and doesn't know what's normal or weird, I worry that chronic issues might go unnoticed as they think that's just normal.

Is there any information out there about what LC looks like in young children, how it affects them, how to recognize it?
