Gift Ideas for New Adoptive Family

Hi All! My former foster placement of twins have been in their foster-to-adopt home for a year now and are going to be adopted soon! I am so excited. We have stayed in their lives, so it has been a WONDERFUL experience for us. Anyways, we have been invited to the adoption ceremony and party and I need some adoption gift ideas. Not only for the family as a whole, but for the big brother and sister (early teens) and for the new soon-to-be-adopted little ones as well who are now 3 - boy and girl One idea I had was a Cabbage Patch doll - do you think that would be appropriate for the little ones?
