Grow Our Family with a Rainbow Baby ?

My name is Stephanie, I have a 3 children, I’m actually married with a great and beautiful woman. We been together about 3 years , and we have decided that we want to have a baby together, she doesn’t have any Genetic Child. We are planning so I can carry her genetic baby. This is the gift that I want to give her, she try before but the pregnancy don’t be successful. This is our 4th attempt. We are already on IVF treatment, but the money factor would be something that could prevent me from giving my wife what she wants so much…”her rainbow baby”. We been already on this process for a year. My kids are excited to have a baby Brother or sister. I appreciate everybody who can help me make my wife’s dream come true. Hugs.
