We never did the sing-song baby talk to DD because she would look at us like we had lost our minds, even when she was a tiny baby. She was always much more engaged when we used a normal tone of voice with her. A couple of my friends commented that we talked to DD like she was an adult, and I told them "But she looks at me like I'm stupid if I don't!" so they tried it and they looked completely shocked and told me I was right. smirk
