So, my older boys are 4 and almost 6. Yesterday, they were playing under one of those little "jungle gym" type toys for the baby. One was pretending to be baby and one was pretending to be mommy. After a minute or two, they both got up on the couch. The 4yo sat up and the 6yo laid across his belly. The 4yo said "it's time to drink!" He lifted his shirt and the 6yo stuck his face to his belly. Then he blew raspberries, but I thought that was hysterical. My boys "nursing" each other. And yes, they took turns.
