I'm looking for a gift for a four year old who's just become a big sister. When my DD was born, DS was given a lovely, funny book called Little Monster Did It that dealt with accepting a new baby into the family. It's now out of print and/or more expensive than I want to pay on Amazon, but I'm wondering if there are any other books around that do the same job. There's no issue with the older child accepting the baby, it's just the general theme I'm looking for.
