One time I was pregnant. There were some simple things that I really wanted from my partner but at the time, I was too emotional to ask for them in a constructive way. Being a parent is a radical experience, and the starting point is the pregnant part. If you can provide an environment that is comfortable to your pregnant partner, the pregnancy, the birth, and the first months of insanity can be greatly improved. I believe that a pregnant woman's needs are totally within the scope of what you can do.
