Photo: Pink's Daughter Willow Is So Ready to Be a Big Sis

Pink's 5-year-old daughter Willow is so ready to be a big sis, as a new photo posted by the singer to her Instagram account proves.

In the too-adorable shot, the soon-to-be sib practices diapering a baby doll. "Dry runs," Pink captioned the sweet moment.

The photo, which comes on the heels of Pink's surprise announcement that she is expecting baby #2 with husband Carey Hart, reminds me so much of my own daughters when they were prepping to welcome a little sister. They started carrying dolls with them everywhere and pretending to be little mommies. I indulged their new obsession, and bought them play car seats, a playpen, a high chair, and a stroller to go along with my purchases for our new baby.

Then, once their sister was born, my big girls were all about helping out. They'd practiced, of course! From giving their newborn sibling a bottle, to fetching me diapers and wipes, to picking out her outfits each day (or each time she spit up or pooped on herself!), I truly couldn't have survived new motherhood with three kids without my mini-rescue squad.

It looks like Pink also has a helper on hand, ready to go! And even though she's only 5, she will definitely be able to help with plenty of baby care tasks once her little brother or sister arrives. Um, she may not want to actually change dirty diapers, though!

How did your older child practice for a new baby's arrival? And how did he or she help out once baby arrived?
