Lyra's is talking and singing

Its so fascinating to watch Lyra develop language. Yesterday I noticed she has been calling water, agua, for a while now I just never picked up on it. You have to be around a small child to pick up their language to understand what she is stating. She has a fairly large vocabulary. I tried listing all the words. It was long.
She is now singing which is so cute. Her are some videos were I tried to capture her singing, speaking and saying one word in Spanish.
First Video- The time I noticed her singing was on our evening strolls. It is hard to walk up hill, sing and record. The videos are not the best because you can hear her clearly.
Second Video- Lyra begins saying no, then says agua (spanish for water), and then she say peek a boo which sort of sounds like, "peektabye".
