Prostitution and pedophilia in this film

Interesting film. These children really had a hard life. Two things I wanted to clarify, though. First, was Pedro's mother supposed to be a prostitute? She mentioned she was washing floors but that could have been a cover story. She also said to the police, she didn't even know who Pedro's father was. And the police reacted as if it was understandable.

Second, in the scene where the young girl sat on the blind man's lap, the man acted kind of strange. He was going to say he wanted something from the girl but was interrupted. Was the blind man supposed to be a pedophile? Perhaps not a full-time pedophile, but behaving like one in this situation. Also, there was a scene with Pedro standing in front of a shop window and some stranger talking to him about something - was that also supposed to be a hint towards child-prostitution and pedophilia?
