Just for fun :) although there is a real baby, it's not the only idea!
DH and I struggling to think of a name for DS3 (!) it took us months and months to come up with DS2's name!
DS2 has pale colouring with red hair and freckles, and cute impish/elfy kind of features. DH has ridiculously strong genes so I suspect the same again. (DS1 has a different dad).
This is an avenue we haven't yet looked down in terms of naming themes and we are both fussy! So hit us with them.
