Nanny Job in Ajax, Ontario

Hi, I'm a mother of 2 and pregnant with my third. My kids are school age 4 and 6 yrs old. Very lovable girls. I'm looking for a part time nanny to come to my house from 4 till 8 pm to help with housekeeping and does my afternoon work while I take care of my new born and help me out with the kids until it's their bedtime. I’m very flexible and would want her to start Feb 3 days a week until I give birth and then into 5 days a week. I prefer a mother but not necessarily.
