The most important person you have to tell about the adoption is YOUR CHILD. This is about her/his life and s/he deserves to know the truth, the whole truth and nothing but the truth.
Everyone else knows! You really can’t be NOT pregnant, bring a baby home as your own and expect people not to talk about it! The real question is – do you want your child to one day accidentally figure out what people have been talking behind his/her back all his/her life? Or do you want her/him to be at peace with this truth so s/he will be able to face life and society wherever s/he goes, long after you have gone?
Honesty is the best policy. The truth will set you free. These are not just sayings. This is wisdom- to make your peace with an uncomfortable truth rather than live your whole life looking over your shoulder in fear that the lies will be exposed.
