Childcare Needed - Full-time / Part-time

Seeking a nanny near Holland to care for my infant (baby #3) when I return to work after maternity leave. I work two mornings or afternoons per week and would prefer to line these up with middle sister's preschool schedule (Monday, Wednesday, Friday). When big brother (7) and middle sister (4) are home on school break, they would also need to be cared for. We are flexible on the location (our home or somewhere else). We are willing to negotiate on pay rate depending on number of children who need care.
