There is no right or wrong answer to the question - to view or not to view. Whilst it is often perceived as an unpleasant experience, viewing the deceased in a calm and tranquil environment can be very therapeutic and helpful to the grieving process. One family member may have a real need to view, another may wish to hold on to living memories. Either way, the option is available and should be discussed openly with your funeral director and close family members.
The embalming process is necessary in certain circumstances, covered in the FAQ section. Your funeral director can guide you, depending on your personal requirements.
