We just had our baby last week and my almost 3 year old DD has been acting out ever since. She’s especially not listening to her daddy and tests me too. She’s demanding things and saying no more than before. Today she even told my husband she wants baby back in my belly and she doesn’t love her. This breaks my heart as she wasn’t like this before. I feel like we are constantly disciplining her. Any advice or comfort knowing it’s just a phase will help!
