Mygirl,
Birthmothers searching for adoptees typically post the date and place of birth of the child.
Also, sometimes, non-ID will have the month and year of the birthmothers date of birth...
If you are in search of the child you placed for adoption, you might consider starting a thread of your own with your information
You can make the subject something like:
ISO Birth son/daughter born XX/XX/XXXX in City, State
That way, if he/she is looking for you, they can find you that way
