Nanny Job in Mississauga, Ontario

I am a career woman and first time mother who has been blessed with a son. My son is an infant that is happy and healthy. He is quite active and loves shapes and bright colors. I would appreciate the nanny to be engaged in my son's development. I also have a dog that will be in the house during the day. He needs only be let out to the back yard occassionally. Finally, I do travel from time to time. Sometimes this travel is a day trip in which I arrive home late. At other times, my travel includes an overnight stay. I would like a nanny that has flexibility to stay overnight to watch my son and dog.
