Baby signing "tired"
Babies give cues when they are tired, such as crying, yawning, raising arms, twisting their hands in their eyes, sucking fingers, and so on.
The time-lapse video shows how the ASL-speaking baby acquired the word "tired". Apparently, toddler can understand the concept of being tired a while before they can utter the word whether in manually speaking or vocally speaking.
In the video, the early "unmarked" handshape first emerged as "flat O" long while before the child can form the correct handshape (bent flat handshape). The location is correct, but at this stage, a baby may not able to (linguistically) cross the arms as in LOVE or BEAR until later.
In my language acquisition documentation, the data shows that the ASL word "tired" and "sleep" were acquired during the one-word stage (12-18 months).
The video shows what how the process of language development (phonological acquisition in particular) works in general. Kids develop at different pace. Note that "baby sign language" is cultural appropriation; ASL signs are words, not "baby signs". Based on scientific studies, language development milestones are on the similar timeline for both signing and speech.
