My favorite is whatever pattern I make for the big sister/brother only done in baby print. I have had Mommies that loved the idea. I find that most of the big kids like that as well. It makes a special connection with the two. If there is more than 1 older sibbling I still make the same quilt in different fabric patterns. I've only had 1 problem from the older kids and that was because they did not like having a new kid in the home who was adopted. The parents had never told the older kids they were also adopted as infants.
