Pitbull advice!

I’m new to the group I’m wondering if there’s anyone here that’s worked with dogs for a while. My moms dog has been acting strange lately and idk what to do. She’s getting aggressive with my son when he’s around me, her bowl, or her toys! Which just this week became a problem. She’s okay with he’s feeding her but he came outside so I can open a bag of chips and before he opened the door she was growling and when he opened the door she went to lung at him. We keep her in my moms room while he’s out playing so they aren’t near each other. She follows me everywhere! Literally she sits in front of the bathroom door she licks my stomach and my chest which is weird to me. Idk what to do and neither does my mom. My son is so scared of her but still want to rub her belly
