Nurse needed - Polanco, D.F. (Mexico City)

Hi all,
Looking for an advice on how to find a nanny without involvong an agency.

I will only need a person to be with the baby for Protected content 2-3 times a week - so basically it will not involve any activities apart from changing pampers and giving milk.

Are there any websites / ads in the newspapers? Or maybe anyone's nanny has some free time?

I will also be glad to meet young moms (or accidental housewives as myself :)) who live in Polanco - for a good lunch or cup of coffee.

Cheers,
Eugenia
