I was a supply teacher, always taking different registers and would just say at the start-'if your name is different from the one I read out, please tell me' and there were generally about 5 who were different-never just one.
Thanks everyone. I am known by my middle name and it hasn't been a problem apart from once - I had 2 sets of hospital records when I was pregnant. So far having 2 names hasn't been a problem - at least at the doctors, health visitors and hospital.
To me they are different names. Cecily is lovely and if she's know as Cecily by everyone then I would put that on her bc. Otherwise she will always have the issue of having 'two names' - one official name and one everyday name.
It is no problem having a variation of the name. I am never known by my full name, in fact I remember MIL being surprised to find it out she had assumed my name was as introduced. I like having an official version and would always use it on certificates etc. it doesn't matter.
Over thinking. Leave it and she has the choice. You will probably find that when she is older she shortens it to something else anyway. You have no control over nicknames. We called DS2 a name that can't be shortened and his friends called him something else - he likes it and the person themselves is the only one with control.e.g a friend had a DS called James on birth certificate and he was only ever to be known as Jamie- when he was 8 he announced he was James and wouldn't let anyone call him Jamie. You are fine as you are- she has the options and she will decide.
I've name changed because I'm outing myself to my family here (hello )
Anyway, this is a slightly different question as my baby is already born - she is 9 months old. At the time, and for a while after she was born, I couldn't decide between Cecily and Cecilia and ummed and aahed over it for ages. In the end I decided that I preferred Cecily. However, Dh didn't agree really! Eventually (because we were getting close to the 6 week deadline) he agreed to register her name as Cecilia, and said he would call her Cecily. He lied a little bit because he attempted (for a few days anyway) to call her Cecilia.
Now she is known by everyone as Cecily. We all love it (although DH would probably still say he prefers Cecilia). I am in a quandary whether to change her birth certificate to Cecily or not. I have done some research and I know that this is essentially the same name (like Elizabeth and Isabella maybe), and I know how it originated. I have seen other examples where people have used it as a nn.
I do like the idea (if its a valid one) of giving her the opportunity to call herself Cecilia if she wants in the future. The other children also want to retain Cecilia - they love singing the song to her! But I can't help but think that it is better to plump for one name. And that Cecily is nicer than Cecilia.
Oh I know that I'm over thinking this - but I'm conscious that I can change her birth certificate until she is 12 months old.
