What do I do???

Pa

He’s obsessed with boobs and will grab everyone’s boobs. Mine, my moms, my sisters, my grandmas, and my SIL didn’t let him and he bit her on the chest 🙃 he’s biting everyone whenever he gets excited about anything and I don’t know how to get him to stop. My little sister has gotten bit by him at least 10 times in these past 2 weeks. Some days it’s twice a day, some days once.
