Chase came with us when we had the first exam; so she had a chance to see her little brother/sister at the same time we did. She had a look of excitement and amazement in her eye. She said, "oh mama!" in the same way she says "oh mama" when I buy her "green juice" (w/spirulina) or "pink milk." Like there was nothing more exciting on earth.
On the way home from the doctor, Chase said, "Mama, baby. Dadda no baby. Chase no baby. Taggart no baby. Dagney no baby." And then in conclusion, "Mama baby."
I asked her if she thought it was a girl or boy and she said, in a way that made it perfectly clear, "Mama, baby."
