Whatever we ask him to do, his flat reply is "No".
Piku, come here - No!
Piku, eat your food - No!
Piku, put the broom down - No!
Piku, sleep - No!
Piku, say hello to uncle - No!
Initially "No" was just a spoken word, later it was conjoined by relevant actions.
Piku, come here - No! (... and run away)
Piku, eat your food - No! (... and clench his teeth)
Piku, wear your cap - No! (... and throw the cap somewhere farther)
Piku, sleep - No! (... and start jumping on the bed)
Piku, give me the mobile back - No! (... and run away with the mobile)
Piku, don't come here - and he would come right to us
Piku, don't drink the milk - and he would gulp
Piku, don't watch TV - and he would switch off the power button immediately
Piku, don't spit out the piece of paper you just put in your mouth - and he would immediately spitThings worked for sometime, but as we all have heard that babies are fast learners; Piku also learnt our strategy and then his responses & actions became conditional. Now he returns our "No" only when it is in his favor.
I think he would grow into a high self-esteemed fellow, because the way he has started returning our "No" sounds as if he is trying to say "मैं किसी का उधार नहीं रखता. ये लो रखो अपना NO"!
