Working Mother is an excellent US magazine aimed at mums who work outside of the home. It covers all aspects of working parents such as childcare, child development and behaviour, work issues and relationships. The associated website gives details of how to subscribe to the magazine as well as quite in depth articles on topics such as family finance, sibling rivalry and top 100 companies for working mums.
