Mums the Word is an awesome newsletter and will soon have a website as well. I don't have the details on what the website will be.

In the meantime, your wife should check out the new mums group, Doha Expat Mums & Kids: http://www.dohaexpatmumsandkids.com The group has an Expectant & New Mums Coffee that meets weekly, playgroups, a private website (in addition to the one above), a Mums Night Out and more. It's a great resource for parents and parents-to-be.
