This is a different scenario, universities have a thing called a 'Follow Through Journey' and they need to meet a quota of women per year to qualify. They need to be with you through all pre-natal appts and the birth. So you get to know them through that. Also you can meet them first and see if you click with them. I have heard good stories and some where it didnt work out (i.e. person didnt turn up to visits), so you need to make sure you find someone you are happy with at the start. They all have different beliefs, experiences and it's good to have someone you feel comfy with if you do it. You dont need to say yes just cos you met them! Maybe you could try a no-strings-attached meeting with one?
