Could you give her another first name? But keep violet as the second name or a middle name, so when she asks as she will at some stage, you haven't completely jettisoned it?
Interesting that people fixate on sleep, feeding and names. I regretted not giving DS his saint's day name, esp as one if my cousins has the same two names. But DH thought four was too many...... No.... I could have given him twenty....
Pretty easy to change at this stage.
What do you think she is like, now? I mean, some babies just do not suit their names at all... I knew a Serena who was the reverse of serene, a Grace who as a child was the clumsiest person ever ( may be graceful now).
Is she twinkly and star like, in which case Stella?
Is she your cuddly little bear, in which case Ursula?
Or with beautiful white skin, so Blanche?
Or tawny, so Leonie?
Or a lovely other flower, like Rose?
Mind you, DS screamed so loudly that the road called him Pavarotti..you could hear him from the far end, so these things shouldn't be pushed too far.
