I can't understand the 'faddy' comments. In 2008 142 babies were named Saffron. The following year this fell to 109 babies being given the name and then it rose slightly to 123 babies in 2010. So actually the name is being used less often than it was 3 years ago.
It's certainly not as 'faddy' imo as Arabella which has risen 97 places between 2008 and 2010. 138 babies were named Arabella in 2008 compared to 218 in 2010. Similarly India rose 81 places between 2009 and 2010 with 58 more babies being given the name than the previous year.
Granted Clementine did rise 107 places last year, however in reality this only amounted to 22 more babies being given the name - hardly a 'fad' imho.
