My silly sister calls my daughter "Nini" which means in Filipino "little girl" (derived from Nene). It's also because the last syllable of her name ends in a "ni" sound. But it doesn't please me so I tell her to stop calling my baby such. But she don't listen. She's annoying ever since. Haha. But then I realized that it's totally fine especially calling a child the way you want it (but not in derogatory way) means you love her :)
Boneneng. It's the Batangas word for Nene. My wife calls my baby Boneng to shorten Boneneng.
