I started off calling her squirt or Little Squirt, but I don't want her to have to explain this to her friends as a pre-teen. When she poops, she squirts and if you don't wait for 2 squirts, you'll get suirted. So now I call her precious and pretty and baby and such. Dh calls her punkin. I often call her Mattie, Mattie. I figured this out listening to Emma talk to her and repeatedly saying her name twice. WHy I do this I don't know.
