My three siblings and I were all removed either at birth or after a few weeks and then placed in foster care for 6 to 9 months before being adopted by our parents. None of us have any issues and we are very close to our parents so it always irks me to read comments that we must be somehow damaged or traumatised by the process.
I'm really glad it worked out for you, I don't believe anyone thinks you must be damaged or traumatised but the fact is, many children are. In your case it would have helped to have biological siblings, all in the same boat and you obviously had good parents. It's just not the same for all, especially those taken away immediately after birth. A few weeks with their bilogical mother is extremely beneficial as long as the child is safe.
Yours story had a happy outcome though and I'm pleased for you.
I generally don't agree with surrogacy. However in the case of a couple who cannot have a child because the mother keeps miscarrying, and nothing can be done to help her carry a baby to full term, if they have someone close to them such as a relative or good friend, who is more than willing to have their fertilised egg implanted in her, that doesn't seem so wrong. She can hold the child and help look after for a while after birth while the parents gradually get used and later on the child can be told that 'Auntie X' or whoever kindly carried her or him through pregnancy because mum couldn't.
In other cases such as one half of the couple being infertile, I do not believe an embryo should be fertilised by a donor or someone else's egg fertilised by the dad. In that case a person would really have three parents and if the surrogate was an anonymous person, that would be an odd story to tell a child.
Sometimes infertility does have to be accepted, hard though it is. There are many who do eventually come to terms with the fact and go on to live happy, useful lives. I wouldn't be so insensitive as to suggest that to anyone though, they have to reach that point on their own.
