"My 3-year-old is biting other kids at school!"

Today on Bad Moms Club, a mother shared the following scenario with us.
I have a problem child and a problem husband. My son is three years old and is allegedly biting other kids at playschool. And, my husband insists on just smacking him whenever he is naughty. He doesn’t hit him hard, but I still don’t like it. He says talking won’t help. So, Bad Moms Club, please help with my biting son and my smacking husband!
