welcome to BB - hope the advice you get here can help you out!

i would suggest not trying to influence your daughter in any way - if you try to push her in one direction (career) she will likely go the opposite. simply support her as much as you can

if she is adamant on having a child with her friend, it would really be little different to any other relationship where the parents don't co-habitate. sexuality doesn't define parenting abilities. i would suggest though that you do all you can to get them to do this through a clinic. at home insemination can be dangerous (no screening etc) - if it's done through an ivf clinic, both will be screened for problems, as well us needing to both undergo significant counselling in regards to the process. it might be helpful to both your daughter and her friend to have an outlet to talk to someone who can be more clinical and de-romanticise the idea of having a child. as you know, it's not easy - and if they are going to co-parent this child, they need to know what they're going into

good luck
