I am looking for a native British or American girl to share hours in the weekend with a short family in Vigo.

I am looking for a native British or American girl to share hours on the weekend with my two daughters (2 &3 years old) and with me, about 3 weekends per month (when my husband is out for work).
The idea would be to accompany us during our daily life, go with us to the park, to the beach, to excursions, to the supermarket ... I would not have to prepare any class, just share our time, help me to take care of them (diner, bath..), and play with my daughters, and teach them games of their childhood.
If you are interested, please contact me for wassap first. 
Kind regards,
