For two years my son called me Mama Bird and I called him Baby Bird (started when he was 2). Now, he calls me Mama Glider, or Mama white Mosaic, and he's Little white mosaic.
We, including my husband, "crab" at each other and Little white Mosaic is often gliding around or building pouches on the couch for himself!!
And of course, we're always on the lookout for stuff for the babies!
