I prefer Cara but DP likes Kara.
Part of me wants to use Kara to go against the grain of MIL as she has not shut up how its a family thing as all of her DC's will have a child with initials CLB (totally unintentional I might add) so K would be breaking that apparently 
I realise that sounds totally pathetic but she is quite an over powering character who would literally introduce the baby with this bizarre anecdote for the rest of her life and I've had enough of that from DS (he shares her birthday) and this is brought up constantly!
So am I being rediculously hormonal by consideting the spelling I'm not overly keen on just to shut MIL up? :o
