This is our second baby and he said that

So my daughter right now is 2 and a half and she's been throwing a lot of tantrums lately and I try to control her without hitting or yelling at her so badly. And when she refused to eat her food today my husband who is not her father but the father of our 2nd baby on the way told me I'm a bad mom and I should let him raise our son on his own cuz I don't know how to control my kids. I am ignoring him for days I'm mad I can't even talk to him I told him he's not the one that has to deal with her tantrums cuz he just walks to another room when she misbehave. I don't even know how to react.
