Publisher's Synopsis
The hit series is back to charm and inspire another generation of baby-sitters!
Mary Anne can't stop thinking about babies. First she starts baby-sitting for a pair of adorable baby twins. Then she and Dawn decide it would be great to have a baby brother or sister of their own.
But Mary Anne learns that taking care of a baby is a big responsibility when she and Logan have to pretend to be parents to an egg "baby" for a class at school. "Sammie," their egg, has to be watched every second, and Mary Anne and Logan barely have time to breathe. Taking care of a baby isn't all it's cracked up to be!
