2nd child, first child acting out because new baby coming?

Shauntelle

I have an amazing daughter who will be 7 this year. She’s a fighter. Came 2 months early. Spent first month of her life in icu. Then back again at 2 months for emergency surgery. At first she was excited to be a big sister. Now she’s behaving badly. Getting in trouble at school, fighting on the bus. Anyone dealing with these issues? If so could use some advice and info on how you’re dealing w it... thanks
