Couples with Babies? Things to do? (São Paulo)

Hi all, my first son was born in February and since we don't have any friends with babies and we are new to all this, I's wondering if you could recommend me activities or places "baby friendly". We live in V. Olimpia, and all bars and restaurants we used to go are too noisy and/or crowded. We found Parque do Povo good to go on weekends and feriados to picnic. Any recommendations?

Thanks!
Federico.
