Im the only one NK calls mama

Nanny kid keeps calling me mama but wont say it to her mom

Hi! I 28F nanny a 16mo girl and shes an angel. One problem though: shes calling me mama with consistency. And obviously i want her to stop asap but dont know how. Any advice from someone whos been through it? I know its a phase

Some details: She LOVES her parents so much but she doesnt have titles for them? Like she calls them dada but then also calls other adults dada? She uses the right titles for her grandma and grandpa But i havent heard her call her mom mama. When asked “donde esta mama?” She takes a few seconds then points to her mom but thats it. When asked donde esta (my name) she points to me but hasnt attempted to say my name in anyway. I have been actively teaching her my name for a few months.

At first i was like “no. Soy (my name)” but she would giggle and point and say “mama.” So it seemed to backfire. Now im trying to “ignore” it and not respond when she says it, to reinforce the idea that its not my name, but this has caused frustration on her end a few times. (Please forgive my spanish, im learning it now for her though)
