Again, it seems that MOST BMOMS REPRESENTED ON THIS SITE were teenagers at the time they placed their children. Almost every bmom I know on this site was 18 or under at the time she placed. However, as DLouis pointed out, the bmoms on this site are not "all bmoms"... only the ones who are computer-literate and are seeking support for adoption-related issues. There are obviously a lot of other birthmothers out there whose situations and attitudes differ drastically from that which is typically described on this forum. It seems this forum attracts a certain "type" of birthmother... those who were generally under 18 when they placed, who care about the children they placed, and who favor open adoption over closed.
It is not a bad idea to keep in mind that there are other types of birthmoms out there, although they are not typically represented on support forums, because they are not seeking support.
Forgive the digression (condetti123); I did feel it necessary to add my 2 cents on this subject, please don't chastise me too harshly!
