Is she talking or are we hearing things?

In the last couple of weeks, Kira has begun "talking"... well, saying words.  So far she's said/we've heard "byebye dadda", "shoes", "football", "bubbles" and "mooo".  Problem is we can't get her to say all of them repeatedly, and they usually come after you say the words and she's mimicking you.  We'll see how her words progress over the coming weeks, and when she starts speaking Spanish!
