In speech therapy, Cece first worked on vowels. Then the Ling sounds (ah, ee, oooh, mmm, ssss, sh). Then combining vowels with opening consonants (bah, mah, lah, whee). We were driving along in the truck, and Cece started saying, very clearly, DA-DE -- two consonants in a row! She has never repeated it, going back to saying DA-EE, but it was definitely a breakthrough moment.
