Toddler bullies

Makaka

How do you deal with a 2.5 yr old who hits and bites and yells? The other 2 little ones in the house(niece and nephew) are picking it up too. I just don’t know what to do, he pushes. Yells no. Tells people to shut up. Hits. Throws things. Kicks. And at points tries to bite when people give him loves. He is so smart and knows he’s being mean. I just am so at a lost and have asked my fb mommy page and all those ladies are either at same spot or hasn’t been as bad as him, and punishing doesn’t work on him😓 sitting in time out or spankings.
