Be chill, let the kitty have space and come to you. Say hi and whatever, but don't chat them up or be physical until they get there. Give them a pick a of cool perches if possible, cats like to be high up and be able to survey from on high, if there are spots like that or where your nee pal seems to be going to as a retreat, this may sound weird, toss a workout shirt near there, they'll get chill with your smell and be cozier with you sooner. All cats have their own personalites and some are just giant cuddle balls from the start where others are more specific, just let the kitty take the lead in the relationship

Saw in other posts you have a kid, if you want them and the cat to have a good relationship, especially for younger kids, they gotta know a chill level that is hard. Once again, some cats are down with whatever, but if they're toonin the kitties face the cat will only hang out with adults pretty much forever and that can be a thing. They require respect.
