Do you feel as though you're a mom yet? Whether or not you're a maternal person, you'll already have started, instinctively, the process of becoming a mother. You may be taking better care of yourself, eating better, and making lifestyle changes, not necessarily to benefit your own health but for your baby. You're likely to find yourself being very protective and nurturing toward your growing belly, wanting the best for your baby, and being worried about anything happening to him. It's nothing to worry about if you don't feel this bond: all women are different and it may not be until you're holding and caring for your baby that you experience strong maternal feelings.
Your partner may not have this strong parental instinct, but the more you involve him in the pregnancy, the greater the chance of him getting close to his unborn child. By reading books or on the internet about how the baby is developing at every stage, and attending some or all of the prenatal appointments with you, he will be able to picture the baby and follow his progress as closely as possible.
