I can't get my husband more involved in caring for our kids, and I want his help. What can I do?

The very first thing is to speak to him and tell him how you feel. Parenting is a joint and shared responsibility, and even more so if both parents are working. I had the same struggle with my husband and a friend suggested that I write down all the tasks associated with taking care of our daughter - right from bathing, to feeding, to play dates, to going to the playground. It helped to see how many daily things needed to get done. We sat with the list and a calendar and divided up the daily caring as well as the taking to birthday party jobs. It helped us both to have a clear schedule of responsibility.
