Part time nanny in Mitcham

Hi, I'm looking for a part time nanny for my daughter aged 19 months, on Wednesdays 8.30am - 2pm with occasional additional shifts on other days to cover for other carers. The daily routine includes giving morning tea, lunch and settling her down for a nap after lunch. During school holidays and occasionally looking after my older daughter aged 5 as well. Experience with preschoolers would be preferred.
