Near names and far names

Apparently L and I both have a pairs of names, according to the little girl. When we are near she calls us dada and mama. When we are far away she calls us by our first names.

A perfect example of this was the other day when L made me a coffee. She asked the girl to call downstairs to me and tell me the coffee was ready. The girl came over to the top of the stairs and called out Bob! Toffee. Bob! When I came in view she said Dada!

I can only guess this is because L and I, tend to only use each other's first names when calling to each other across the flat. Regardless, it's led to a rather cute side-effect.
