Nanny Needed For My Children In Denver.

I am in search of a caregiver who takes care of children in their home with a start date in June or at the start of the school year of this year. I am looking for someone who can for sure start work with the school year but is also available over summer. My sister might move out for summer to help, but if she is not available then we would need a nanny full time starting in June. I should know by the end of the month if she will be here this summer. My daughter was born in December, in June she would be 5 months old, in September nine months. We are looking for someone w/ experience with babies. If they are watching other children, ideally they are also babies. I'm hoping for someone who will help with engaging activities and "exercise". We are doing formula so also keeping a routine schedule of eat, play, sleep throughout the day.
