UK Passport for newborn baby-any one gone through the process recently

Hi All

Me and my wife are British citizen we aquired our British nationality through naturalisation ( both of us born outside of UK). We have a 6 year old boy born in UK and got his British passport. We are now expecting our second child soon (in Mauritius) and I am at a stage of  gathering all information to make application.

Has any British expat in Mauritus has recently gone through this, and provide some important advice on the documentaion or any other fine/minor detail that I should be aware of. I will appreciate any advise.

Best Regards
