surrogacy

I have this wonderful friend. She has been tryin for nearly 10 years to have a baby with her husband and for 10 years she has been let down. Fertility treatments and medications and so on... all have failed. I know she would be a wonderful mother and wants to have a baby more than anything in the world... so I decided after I deliver and recover I am going to offer to carry for her. I think that if I can make it through this pregnancy with no complications then I am going to attempt to give her the gift of a child. I know it's a big commitment and it's not a choice I make lightly. My husband and I have talked about it for about 2 years now. I deliver in June and I think maybe by January of 2018 I would be ready to carry for her. She deserves to have a baby of her own more than almost anyone I know. What are your thoughts?
