But I can't ever seem to pin them down, they're freaking in their own world, one second they're all soft next second they're acting crazy and like ughhhh please help me OUT y'all. Give me some tips or something because I wanna have a blub blub🐟 boy, without having to feel like i'm going to wring his neck before he snaps mine.
