The birth of a child represents one of the more crucial days in every woman's life. Ground-breaking because the family becomes richer with a new member, but ground-breaking also in terms of a woman's hormonal balance, which is subject to rapid changes that can result in postnatal sadness and even depression. Both of these conditions can have a negative impact on family life and mother-child relationships, so it is very important to recognise the symptoms and take appropriate steps, i.e. to visit a specialist and receive treatment.
