My crush laughs when he heard my laughter?

I've noticed at least two times now that when my crush hears my laughter, he will laugh in an amused way that somehow is obvious that he's laughing bcos of me and not the funny thing that was being said by our friend

I don't have a weird or funny laughter, but I do sometimes laugh like a little kid. Like it might sound cute and childish at the same time

Is this a good or bad sign that he laughs when I laugh?
