Emma,
You are a truly amazing, loving beautiful woman. I am weeping after reading your post. Abbey is truly a very lucky little girl. I am sure she will give you so much joy and in return you and your husband are just the parents she needs.
Please take someone to support you and your husband today. Sometimes these medical people can be very decided what they think is 'right'.
You have made your decision and just ask that your decision is honoured.
With lots of love,
Deb
