Nanny Needed - Full-time / Part-time

We are the grandparents. We are watching our grandkids 4 days a week. We are expecting 2 new grandchildren in the next year in addition to the 2 we have. One will enter preschool next fall, so we will be responsible for 3 kids under 3 years of age. We would like some help playing, teaching and entertaining these babies. This would be a 2-3 year endeavor and could be 15-25 hours per week. We can be flexible on specific days and hours.
