ImNotReallyReal absolutely no one thinks your view doesn't count and thank you for your kind words. 
It's very difficult because things do change very quickly, or seem to. I adopted 3.5 years ago and I am in England so things are different to Scotland, I am told.
thomasmuggit I would agree that "Relinquishing does give you a louder voice than having a child removed," and also that "...in the end, social workers will choose who is your baby's family."
However, relinquishing does at least give you the option to change your mind, where as having a baby or child taken away does not.
Also, adoption is an alternative to termination or single parenthood, it is a choice for those who choose to relinquish but it is very rare in the UK. I guess like other not-ideal choices it may well feel like no choice at all. However, I think that view could be dis-empowering. There is a choice.
I am surprised to say I do know two couples who adopted relinquished babies in the UK, I may well think that is quite unusual and many may not know that number (relinquished in the last decade). But it absolutely is not like the US, where pregnant women select a parent/s for their child.
OP would it help you to explain why you feel relinquishing your baby is the best way?
"The father and I are not together and as I am only 19, we are looking through my options." The father is older, would he support you if you kept the baby, what about your family?
It may seem curious that I (or other people who have adopted) would appear to want to talk you out of relinquishing your baby. I don't want to do that if that is he only or the best option. I just want to make sure you know that is really best for you.
