Is it true that a baby makes or breaks you as a couple? My neighbours never used to argue but since they've had a baby (about 2 months old) all I can hear is them arguing. The baby cries almost non stop, and its a constant screaming cry. Does my head in and I can hear him faintly through the walls, so it must drive them mental! So, is it true that a baby can break down a relationship? I've never had one but wondering if that's whats happening to the neighbours.
