Thoughts on managing position sizing for less liquid small caps?

I've been dipping my toes into some smaller cap stocks, mostly looking for potential multi-baggers that seem to be flying under the radar. The usual advice for position sizing, like a fixed percentage of capital per trade, makes sense for liquid stocks where you can get in and out without much fuss. But with some of these micro-caps, even a relatively small position for me can represent a decent chunk of the daily volume, especially if I need to exit in a hurry.

I'm finding myself hesitant to put on the size I'd typically use, even when the conviction is there, because I'm worried about moving the market against myself on the entry or, more critically, getting stuck on the way out. This is leading to smaller wins when I'm right and still the same percentage losses when I'm wrong, effectively lowering my overall P/L. Are others just accepting the lower sizing and slower accumulation/distribution for these types of plays, or is there a different approach to risk sizing specifically for illiquid assets that I'm missing?
