english or french native speaker for a baby (2,5 yrs old) twice a week

Hello, I'm looking for an english or french native speaker (or both) to play with my son twice a week. It's not really a babysitting (there will be always somebody at home) and not really serious lessons (my son is only 2,5 years old) - just play together in english/french twice a week (1-2 hours), possibly in the morning. We live in Powiśle, near Most Poniatowskiego, Rozbrat, Bulwary Wiślane.
