Nanny in Winnipeg, Manitoba

I am a high school student (currently in grade 12 graduating this June 2016) and I can be a babysit after school. I am not an official babysitter but I can say that I have enough experience to babysit because I have a 7 year-old sister that I've been taking care of/babysitting since she was born and I also have cousins about the same age as her that I look after sometimes.
