Pregnant with surrogate gift

C

We have a friend couple who called up and want to come visit us in the next two weeks. We know they were doing an embryo transfer with their surrogate a week or two ago, sooo we think they have good news and wanna tell us in person. IF that is the case, we want to have a gift for them if they tell us some good news.

What is a good gift for a couple expecting through a surrogate?
