Children born in Switzerland have no right to Swiss nationality. Your child will be Indian just like you & your wife. The big advantage here is the standard of care, I have no idea what hospitals are like in India but here they tend to be better, in my experience, than the UK. Also consider how much time you would need to be apart, your wife would not be able to fly without a Dr's cert after 7 months and it is probabl that for long haul the Dr would/could refuse to issue one for medical reasons.
