Babysitter wanted for childcare in Calgary

My name is Maria, and I have two children one is autistic. he is verbal, calm, and enjoys playing games on his iPhone. Im looking for a flexible nanny who can care for them for a few hours whenever I have last-minute appointments or errands. The care will take place at my home, and everything will be sorted and organized for the kids. They are independent, but I need someone who can supervise them, keep them hydrated, and provide snacks as needed. Cooking will be very easy just quick things like grilled cheese, sausage, yogurt, or a few simple snacks nothing complicated. There is no fixed schedule, so I need someone who is really adaptable to occasional, short-notice requests. If care is needed in the morning, it will only be for my son, as Halima is in daycare. Please let me know if you are available and interested!
