What is it that makes you really want a baby? Ask yourself this question, and jealousy from seeing other mothers is not a good reason. Although I understand, that if your boyfriend doesn't want one then I see where you are coming from. Just remember that it can definitely change a relationship..even a marriage. I have to agree as a single mom now, (I had my son at age 20) that a child changes everything and it's more work than you realize. Although I wouldn't change a thing, it does change and did change my relationship. If your boyfriend doesn't want a baby..then this is important to discuss and it's best when both people want one otherwise it could cause potential problems and added stresses.
