One thing you may not have anticipated before you were pregnant is how your friendships might change. It's normal to be drawn to other women who are pregnant or who have recently had a baby, and common to make friends at prenatal classes (see Classes for two). It's natural to want to surround yourself with people who are going through or who have been through the same experience as you, not least because you will have so many questions they can answer. You might also feel closer to female relatives, especially your mother (see You are 19 Weeks Exactly).
You may find that friends who are not pregnant or who don't have children may not be as interested in all the details of your pregnancy. It may be difficult for them to comprehend how all-encompassing pregnancy and then having a child is; it may be literally all you can think about. If these are friendships you value, make an effort to have some "nonpregnancy" chats. It will be good for you not to be 100 percent focused on the pregnancy.
If you find you drift apart from these friends for a while, don't worry. Good friends will always remain just that, whether or not your lives temporarily go in different directions.
