Rock-a-bye Ian is an adaptation to the rock-a-bye baby rhyme that Chloe and Mommy would sing to Ian. The second half of the book allows you to make it your own by adding the names of your children. You can also glue or tape in photos of your family to go with your individualized story. This is a perfect activity for you to do with an older sibling upon the arrival of a new baby. OR add Mommy or Daddy at the end to catch baby!
