Piku loves Mummy

My kid has recently learned a new word "Mummy"! Whenever he intends to summon his mom, he would shout "Mummyyyy......" (of course) and then he will utter something in his own lingo which no one can understand; & again shout "Mummyy......"; & keep doing this till he wishes. Cute, isn't it? Well, not always.... & I learned that yesterday only.

We were in a so-called hep shopping mall, surrounded with many so-called hep people (coated with an extra layer of fake-sophistication), when I heard Piku's familiar voice reciting "Mummy... mummy... mummy... " on top of his lungs.

First thought (admiration): "How sweet"
Second thought (confusion): "Why is he calling his mummy; he is already with his mummy"
Third thought (more confusion): "Why is everybody smiling at us, especially me"
Fourth thought (panic): "O God! He is addressing me as his Mummy!!!"
Fifth was not a thought, it was a sentence that came out of my mouth (hasty reaction): "Betu, Papa. Paaaaapa. Say Paaaaa...pa..."

But the trick backfired; Piku turned towards his mom & started chanting "Paapaa papa papa..."!

Now by default, both of us are summoned as "Mummy". If we interrupt, then only either one of us randomly (& optionally ) gets addressed as "Papa" for next few minutes.
