How do I tell my boyfriend I want to have a baby?

A woman should be not afraid to ask for what she wants. If its a family you seeking in a relationship you should go up straight and discuss how you both feel about it.

I'd start by asking him more generally how he feels about having children--if he'd like to have kids someday, what his opinions are about how to raise a child, etc. Based on the answers he gives you should have a good idea as to how your soon-to-be stated desire will be received.

I would tell him that I would like to gift ourselves for the love that we share by inviting a new member into the relationship who will take us to a next level of happiness.

Try talking to him and explain how you're feeling and why do you feel like having a baby would be a good idea. If he doesn't agree, listen to his opinions and don't start a fight, and solve the problem like an understanding person.

Tell him you love him and are happy too, but having a child would make you even happier and bring you both great joy. Try to see his point of view though.

Honesty is the best policy. Open communication is essential for every relationship, not just romantic ones. Having a conversation with your boyfriend about your feelings and needs may be scary, but he is not a mind reader. Informing him of your needs is the best policy. A baby is a big commitment, so perhaps come into the conversation with responses to potential worries he may have (such as "how will we afford this" or "we work so much"). Having some answer ready for him will help show that you are serious and mean business, so to speak, which should help him feel more comfortable with the idea.
