Learning words - quickly

Sydney is learning new words/phrases almost daily now. The most recent is "I Love You" although it sounds more like "Uv ew", but we all now what she means. She likes to pick up the phone or the blackberry and babble to someone, she has the pauses and responses down as if she is having a conversation. For bye she says "dye", ask her if she wants something and its a clear "yes or nooooooo" (with an added shake of the head - especially if she is not ready for bed). Seth is Seph, Mom is Mahm, and Dad is Dah - all yelled out especially when we are not in the room.
