Part time nanny starting in May

We are looking for a baby sitter to help with Amelia (13 months) and Theodore (almost 4) 2 days/week starting in May. A WWCC, police check and parent references are required. I may be home on some days (but working) and on other days may be in the office. We also need someone who is comfortable with animals as we have a dog. We are located in Altona. Our children love to be outside and to do activities, so someone who I happy to take them for walks to the park / beach is ideal.
