I'm looking into the option of an au pair to help out with my daughter, who would be 3.5 by then. I also have a baby who will be 1 and I will put him into nursery as I think it's too much to expect an au pair to cope with a baby.
Is 3.5 too young too? I would need her to do wraparound care for preschool for the summer term (so outside of 9 to 3, and one afternoon, four days only) and then some full days of childcare over the summer.
