One of my favorite things she says is "much fun" instead of "so much fun". My favorite time she uses it is when I lay on the floor and cuddle with her at bedtime. She'll look at me with a big smile on her face and say "much fun!" When she says that I hear "I love you". (btw, she sleeps on the floor and has completely given up on the toddler bed, and I'm mostly okay with that).
Sometimes we take walks on the bike trail where she walks instead of riding in the stroller. Whenever she sees someones about 20 feet away she'll start waving her hand enthusiastically and start saying "hi" in her deep voice. It's so funny. The old people love her!
She just looked out the window and saw a dog and she started saying "hi" in her baby voice (similiar to how we talk to babies). Then she said "toot doogie" meaning "cute".
(This was taken probably sometime in the fall)
