Defiant children

Melissa

This is not about the baby that is in my tummy, but I have a 5 year old and the further along I get in my pregnancy the more defiant she becomes. She will openly do what you are telling her not to do than when she gets mad she seems to always wanna hit my tummy. Is this normal for only children to act out like this? We have been doing everything we possibly can to help with the tantrums but I’m at my wits end with her hitting and knowing she could hurt her brother... anyone have this happen? And any good tips? I’m terrified that she’s going to hate her brother once he’s here because a lot of attention will be on him.
