Over here we've got "UP!" accompanied by arms up in the air and an expectant look.

No "mummy" or "dadda/daddy" but there is the usual mumumum, dadada, tata (with bye bye wave) and plain old ta to indicate she wants something she's pointing at. She does a very cute mmmmm! when food comes out. Also tries to say pet names. Puh-puh for our cat Asper and apparently she's said SIL's dog's name, Axle, but this has never been repeated.

I too cannot wait for those toddler convos!
