Daytime care for an 18month old, 2-3 times a week

Hi there, I'm looking for a babysitter to care for my 18 month old. Starting with 3 x a week for 3 hrs a day and most likely dropping down to 2 x a week for 3 hrs at a time. I'm flexible between it being on Monday, Wednesday, Thursday, or Friday, and timings could look like either 8am-11am or 1pm-4pm.

Need to be ok with big dogs as we have a female german shepard who is really just a big teddy bear at heart.

My daughter is a very active and curious little human. Care would be at our home in Innaloo and maybe walks to the local park once we are comfortable enough with a carer.
