Toddler using interjections in sign language

Toddler nodding as a visual "uh-huh"

More than "yes", the toddler Juli (age 2;4,1) began to use the interjection that is equivalent to "uh-huh" and its affirmative variants more often in the past few weeks.

Before that, Juli nodded as in "yes", the opposite of "no". Now lately, Juli nodded on a deeper meaning beyond "yes". She nodded in the form of "uh-huh", "yeah?" and other affirmative variants at the end of a simple sentence.

When Juli wanted something, she asked for it in ASL with a nod at the end of the sentence. It's like "okay?" or "yeah?"

Juli also sometimes thought for a moment and nodded to herself which is equivalent to "mm hmm". The other day Juli squatted and watched ladybugs doing their business. Juli silently thought to herself and nodded "mm hmm". I don't know what she was thinking about.

The emergence of ASL interjections "hmm" and "aah"

The interjection intj-hmm emerged in sign language that Juli (age 2;8,1) used often. E.g. ix-me want intj-hmm... chocolate! (her strategy to convince me), another one.. hmm.. (pointing to the another art supply), .

Shortly, Juli added a new interjection aah in her daily language. Her typical ASL utterance is like ix-me want, hmm... aah! candy.

It was her way of making it a suspense. Every time she did, she got my attention with curiosity as to what she was asking for or what she wanted. With the interjection "hmm", she made me curious or wonder, listening to her. With the interjection "aah!", she got my full attention.

With these interjections, her intonation also developed along.

A week later, I asked which banana or apple (for breakfast) she wanted. She replied, hmmm... ice-cream!. I told her no way. She explained, funny+++ with body ryhthms and laughed.
