Couples are always thrilled at the arrival of a new bundle of joy, but when it is your first child the adjustment to becoming parents can often be very stressful. You have become accustomed to the dynamic in your relationship when it was just the two of you. Now suddenly there is a third person and it changes everything. It changes the way you view yourself and it may even change the way you view your partner. This new person puts new demands and new pressures on the couple and the whole role of parenting places a new type of strain on the relationship.
