Brief background:
I'm married but have retained my surname. Have toddler twin DSs who will be our only DC. For us, its not necessarily automatic that children take their father's, as opposed to their mother's, surname but in the fog of early days parenthood we ended up going with DH's, a decision I now regret...
DH surname is one of the top 3 most common in the UK. DSs do not have very unusual first names, so we now realise that their full names sound very...ordinary. My surname is quite unusual; not tricky to pronounce/spell or posh, just quite rare. I want to change their surname by deed poll to mine so they aren't one of a million so- named kids & to help them be more identifiable & unique. But I'm worried that they will then have different surnames on their birth cert than their passport, for example, & they might not understand why or not like that, as they grow older.
AIBU to change their surname?
(I'm canvassing opinions on the potential name CHANGE, not the wider principle of whether a child should take their father's surname automatically ).
