How difficult is it to change my dd's name?

[mrsshears]

dd3 is 5mths and I'm regretting not giving her my late grandmothers name as a middle name, how difficult would it be to amend this?
Thanks

i'm not sure, but I think you can change their name up to a year just by having the registration changed. You should ask them.

I believe you can just to to the registrars and change it.

Yes - I think in the UK it's more of a palava after the baby turns 1yo.
