Yes/No

I am almost 1.5 years old but not yet really can talk yet. I do make sounds like a sentence but no one understand.

I just learnt how to nod my head to express 'yes' and shake my head to say 'no'. In the past few weeks, I have confusion on using of the above. Shaking my head is much easier than nodding so no matter what my mom and dad ask me, I just reply with the easier sign I know.

Today, dad reinforce the association of 'yes/no' with 'nod/shake' by giving/not giving the toy I want and I quickly figure out the right message I need to send out. Although my effort to make my nod is much bigger than shaking my head, I do express myself correctly.
