Sometimes an au pair is a great option, not always considered for childcare. Keep your children at home, no packing up everyday and germ controlled. I have some friends who have tried this and been very happy.
There are many quality child care options available in Hunterdon County. I have an "in-home" program. I know there are many other "in-home" programs as well as larger, center type programs and I would be happy to share contact information.
