Okay. Jillian's been saying, "ma ma", "da da", "neh neh", and "ba ba". We're quite sure these are arbitrary ramblings of a baby. But this morning she looked at my coffee and said, "da!". The boys and I looked at each other and Miles said, "She said 'that'." Well, I thought I heard the same thing, but doubted the probability of such. And then moments later she looked at my coffee again and said, "dat!", actually pronouncing the 't' sound. We looked at each other and Avery said, "that's weird". Could it be?
