Watch in Video 174 what happens when we pretend to ignore Natalie while she's sitting trapped in her highchair (she loves her IKEA highchair by the way). At first Natalie and I will chat together and I'll be interested in her, but 30 seconds into the video, I pretend to turn away and be busy with something else. She will play with the objects nearby, pretend to drink water, and then attempt to start conversations with us. It's pretty funny and really hard not to look at her and laugh when she chatters a string of syllables (can't make sense of what she's saying at all).
Also, see Natalie in Video 175 as she calls herself "Nat-lee" and points out her shirt is dirty (from lunch). She is super cheerful and playful with her daddy Clark.
