Wow D & M, you guys certainly sound like you are ready!
Good luck with it all, just a small word of caution, be as clear as you can possibly be with your donor because conception agreements, even if drawn up with a lawyer, can still be overturned by a judge, particularly if the judge is 'old school' and believes in 'traditional families.'
This doesn't always mean that the father sues for custody, sometimes it translates into grandparents or siblings of his sueing for rights to the child and the younger the child is, the more likely that the judge will grant some custody to them. It's an unfortunate side affect of the refusal of the law to recognise our families and accept that, yes, a child can be as loved and nurtured by two gay women as by a man and a woman in a 'traditional' family environment. Until the laws change to reflect that our familes exist, it's quite scary that someone we either don't know well, or in some cases, not at all, has the right to take our child out of our house for three days a week just because they donated sperm in a kitchen instead of a clinic.

Anyway, all that being said, I am soooo excited to welcome another lesbian family!! Good luck and we will be waiting eagerly for the OMG! We're Pregnant!! news
