In response to what someone else said, a woman is not being selfish by wanting to keep her own child. In the cases where a sibling is involved as well as most others, it is selfish to give her away. You can provide the best for your little one. Your child already knows you a his or her mother and trips to disney world is not going to change that fact. Ask any child who has grown up what they would rather have one trip to disney world or to be with their parent? They will all say to be with mommy or daddy. Your seven year old will also be traumatized by this always wondering when you are going to give her away too.
And college can be free, that is a silly thing to give a kid away for. I went to college with no costs at all. I didn't even need to pay for food or textbooks and I had money left over. (And I had kids!)
It is very possible that the people you want to give her to will end up on welfare! They can get divorced like any other couple and your child might end up being the reason they divorce! It is very likely that your child may not ever go to disney world with these people or go to college. And they can not provide the same love and bond that you can. There will always be a disconnect, there will always be something just not right to your child.
Also, with things like adoption you should always be 100% sure you want to do it. Just asking this question proves that you do not want to adopt and you want your baby just like he or she wants you. That couple could have adopted ages ago, but they are the selfish ones refusing to have a family that may not be ideal through going through free foster to adopt.
Your doctor faces charges on ethical grounds. I would report him to the medical board. He may say it is your choice, but he really does not mean it.
Also, if you really do not want her (which is what adoption is for- children who are not wanted- not some fairy tale oooo better life and rainbows and unicorns It is for orphans and unwanted children end of story) than what about the dad. Do you have his permission to give his child away? Or are you going to commit fraud in court and potential charges of perjury to say father unknown? Also, are you expecting open adoption? Because it is not enforceable and it is a bunch of lies!
I know you are pregnant and reading this may seem harsh, but pretending you do not want your child for the sake of someone else is a harsh thing to do to your child. Please read the truths that many people post on this board about adoption, please read that many people regret this choice and many people hate the fact that they are adopted. You can be the best mom for your child! Nobody can replace you! If you are eligible for SSI, you are also eligible for food stamps, housing assistance, college tuition for yourself (through TANF or pell grant there also many local programs out there), daycare vouchers, clothing vouchers, furniture vouchers, many charities, and the list can go on. Take what you can get including the free college tuition and daycare vouchers and fix the problems that you are so worried about. Your child will thank you.
