We were watching the "Sound of Music" this evening. At the end of the "So Long, Farewell" song when Gretl pretends to fall asleep and Liesl comes down to carry her upstairs, David get really excited and stood up to shout "Her Alyssa picked her up!". We all laughed about this newest entry into David's thesaurus.

It's so cute to see kids exploring the magic of languages.
