Just a few I can think of off the top of my head...
arf-arf = dog
gitty = cat
ticky-ticky = tickle
e-in = airplane
uck=truck, duck, or yuck depending on the situation
ock= rock or sock
ainain = raisin
ba-ba= cup, juicebox, water bottle, etc.
deeshee = baby
up-da = up, down
dutton= belly button
eas = ears
ice = slide
stink or yuck = messy diaper
boom=a sonic boom, something falling, a pillow
nana-nana-nana...= banana (this goes on until she gets one)
eesh = cheese
duck=anything with a beak or bill
She will use all of these in sentences too.
For example, if she sees Reagan's dog food: "Dat arf-arf numma-numma!!"
Or, pointing at the sky: "Moo!!! See moo??"
Or, going to bed: "night-night Deeshee, night-night fish, bye-bye ight"
