(Visiting from the UC forum)
Here's a link to a great article on pregnancy and IBD. You have to copy and paste it into your browser as clicking on it doesn't work for some odd reason.
It covers a lot of things, including breastfeeding and it's potential effect on flaring, as well as medications and breasfeeding.
Mods, this article is in the UC resources thread on "our" page...maybe you'd like to add it to the Crohn's one as well? :)
