S.N.
I think she's just wanting more attention. She gets used to it just being you girls, then has to adjust to it being fmaily life again. I would talk to the teacher, and make sure she isn't demanding too much attention at school too. Assuming it's a home only issue, I think the only thing you really can do is try to schedule an hour of one on one mommy/daughter time, doing whatever she wishes(within reason or course), and also try to lace in some one on one step-daddy/step-daughter time and hour each evening that he's home. Our maybe even an hour or family time instead, where she is the focus of all attention from both of you. Being a five year old, she undoubtedly must have an early bedtime. You and the hubby should have plenty of time alone after the happy little girl is fast asleep.
