Nanny Needed For 1 Child And Afterschool For 2nd Child

We are seeking a full time nanny near WDM for a 3-month-old and afterschool care for an almost 4-year-old sibling 2-3 times a week. Older child attends Montessori preschool and will be off school at 3 p.m. It would require pick up and caregiving of the older child 2-3 times a week, the other days my in-laws will take him. I work from home full time but need help taking care of the kids during my work hours. Looking for someone who has experience in young infants/children. We are flexible with the start date but aiming early June as I return to work full time early July. Some light tidying up, kids laundry, and planning activities would be part of our caregiver's responsibilities.
