Each cemetery operates differently. Some cemeteries will allow burial on a family member’s grave with permission of the family, some will not. Some cemeteries have “Baby Gardens” designated strictly for babies. One may find a cemetery that charges the same for a baby burial as an adult, while others offer space charging significantly less or nothing for babies.
Call around to get specific prices and information from cemeteries, and be prepared for a variety of results. Know that there is often a price for the ground and a price to open and close the grave.
Most, if not all cemeteries, are unwilling to give the grave marker for free. You may find that Catholic and other religious cemeteries charge less for baby graves than their public counterparts.
If you decide a cemetery burial is not feasible, then a home burial may be your only option. Be sure to check the laws in your area that govern this. Laws regarding miscarriage are less restrictive. Information on state laws can be found on this page: STATE LAWS.
Prior to digging on any property, be sure that your burial site is not over any underground dangers such as buried wires, gas lines, etc. Also, be sure to mark your burial site with some sort of permanent marker. You may consider burying a large metal object a few inches under the ground and over the burial site so that it can be detected with a metal detector at a later date.
