Angelina Jolie and Shiloh Jolie-PittAfter two years as the baby of the family, Shiloh Jolie-Pitt is reportedly adjusting to the idea that she’ll now be a big sister to some of her siblings as well as a little one.

A source close to the Jolie-Pitt family told OK magazine: “It took her a while, but now she’s as excited as the rest of the family.

“She puts her hands on Angie’s stomach to feel the twins kick and she jumps back and starts grinning!”

The source added that Shiloh is preparing to take to her big sister duties seriously and is pushing forward with her own development: “She’s got her pull-up diapers and tells Mom and Dad when she has to go to the bathroom.

“She’s trying to get the hang of it all on her own - just like she did with walking.”

Mum Angelina Jolie is expected to give birth to twins in August. The babies will be Angelina and partner Brad Pitt’s fifth and sixth children.
