I also agree with the above answers and feel this is probably happening due to the new baby.
Have you allowed her to interact with her new sister?
I allowed my daughter, who was 3 yrs old at the time, to be a big sister and a big mommy's helper when my son was born.
I'd let her hold him in her lap, hold the bottle while he was eating, pick out his cloths, help change his diaper, sprinkle the baby power, etc,etc...
I took lots of pictures of both of them together and would make a big fuss over what a beautiful big sister she was
And gave her a little photo book filled with pictures of them together.
She was very proud of her pictures and loved showing them off to anyone that would look.
Everything I did with her before my son was born, I just continued on doing except with a baby in my arms... LOL
It was really quite simple and my daughter never had any of the set backs that some children do when a sibling is born.
I'm not absolutely positive that including her with everything contributed to good, helpful behavior or if that was just how she was on her own.
Just try including your daughter in everything that you do for your new baby, ask her if she'd like to help, or if she asks to help say yes.
If she feels that her new sister "needs a big sister" and mommy "needs a big helper" and she has a "responsibility",
Her bad behavior may turn around as she must "set a good example"... It's worth a shot... it worked for me... I think.
Congratulations on your new baby and good luck with your 3 year old...
Mine are 3 years apart... You're going to have lots of fun when they are 7 and 4 ;) :D
