At forty-six weeks, Jonas is: trying out a few new foods (black beans, rice pasta, and cauliflower); experimenting with the use of his two bottom teeth for chewing; adding three words to his vocabulary (“ca” for cat, “boo” for book, and “ba” for ball); and cracking us up with his current favorite consonant/vowel combination (“da-da-da-diguh-diguh-diguh”) that he repeats over and over again in all seriousness and with much gusto.
