When my wife was pregnant, she would enjoy a Shandy Bass. They're actually made with Bass, but it's only like 0.5%. We used to be able to get them at a local Irish pub near us. I don't know where you'd find it around here.
When we were in Scotland, a very popular drink with pregnant women was a mixture of something called Sweetheart Stout

Sweetheart was in bottle and Tennents was on tap. It wasn't great, but it was better than nothing at all. The stout is like licking a bar of molasses without the bitterness and then dump about a pound of sugar in it. You NEED the Tennents to cut the sweet.
