Baby sitter to play and look after 12 month boy with mom - Full-time / Part-time

Hi we have our son born last year, and we need someone who could help the mom taking care of the baby. Play and talk with the toddler kid with his mother. Diaper change and meal feeding would be huge plus, but basically just play with the kid in the living room area. We are locating in the Fitzroy San Marcos, which is a awesome neighborhood.
