hey mama's,

I'm in a bit of a dilemma my 10 month old is being so soooooo bad im not trying to be dramatic but he is very naughty when we tell him not to hit or re direct him he always hits back harder and starts throwing a tantrum. he's also learned to bite when he doesn't get his way. he's mean to everyone that holds him. either hits, bites or attempts to scratch them for a while I thought he didnt know what he was doing. but he's doing it on purpose bc every time we tell him to stop hitting and show him how to be nice he either does it again and looks at us defiantantly or he throws himself back and screams. any advise
