Surrogate Mothers

So, this is some information regarding surrogate mothers:

• Surrogate parents can change their mind and keep the baby (and courts will probably be in their favour)
• The surrogate mother's partner will be the automatic father of the baby, genetically related or not
  
  

I've actually seen a case of a surrogate mother on the show 'Hollyoaks' where she loved the baby (but eventually gave it up because the woman she was carrying it for was her friend). But in general how do you feel about this topic? I personally find it wrong given that the person would be waiting with anticipation for nine months only to find that the surrogate mother wants to keep the baby..
