Raloose

Emma is a big talker. She sits in her crib every morning talking to herself and, when poopy, yells "Stinky Yucky!!!"

All of her words, if not perfect, are at least recognizable, or referencable. For example, Emma calls her belly button her "bing bong". This makes sense to us becuase we poke her in the belly and say "bing bong".

However, there is one word we just can't figure out. We know to what she is referring, but have no idea where the word came from. Raloose (pronounced ra' . loos) means water. When we tell her to say water, she clearly annunciates the word "water". But whenever she wants water, or more often, some of your water, she calls it "raloose". She know and correctly uses the words drink, milk, and juice, and water is always raloose. I have been trying for weeks to figure out where this came from. Ice? Ice water? Thirsty? I can't think of anything sounding remotely like raloose.

Can anyone help me figure this out?
