I need

Advice... how do you get your toddler to stop putting his hands on you and or screaming on the top of his lungs when you tell them no? If I pop his butt for it it makes him really mad and he’ll hit me harder , putting him in the corner doesn’t work either... I’m fed up 🤷🏼‍♀️ no there isn’t any abuse in this house but there has been change his dad just started to become a truck driver so he’s gone all week and it’s just me and my two kids which Ik is a big change for them but he still don’t need to be hitting or screaming at me he’s 2 and my daughter is 1 now she hits because he hits her so now they hit and pull each other’s hair and hit me idk what to do
