Likely the most common arrangement in open adoptions is for the adoptive parents to commit to sending the birth mother photos of the child (and themselves as a family) each year, and short written updates, until the child reaches the age of 18. Often these photos and updates will be sent more than just once a year, such as the child's birthday or other significant events. Sometimes an intermediary is selected to receive and forward the updates, and sometimes it is done directly. This can be through mail or email. Some adoptions are more open than just sending photos and updates and include face-to-face contact. The amount of contact can vary greatly from just once in the first year, to multiple times annually throughout the child's life. Some of the adoptees raised in open adoption are now in adulthood and are writing about the experience of growing up in an open adoption.
Most open adoptions lie somewhere in the middle, according to Grotevant and McRoy, exchanging letters, pictures, and phone calls, and having face-to-face meetings once or twice a year. Whatever their situation, many families report that relatives and friends condemn openness, and voice fears that the arrangement will make the birth parent want the child back.
