Long story short - she has a 7-month-old son called Matthew and is 5 months pregnant with another little boy. I have a 2-month-old son called Jimmy.
I say cousin, she's actually the half-sister of my second cousin David and thus not actually related to me by blood but the families are very close-knit and being a similar age (I'm 20, she's 22) and with similar interests, we're very good pals. We spend a lot of time hanging out with our babies and whenever she's in my vicinity (or I'm in hers) we'll head down to the park for a "baby picnic". Very therapeutic - much recommended by the way!
Anyway, I digress. After not minding it too much a few weeks ago, quite liking it a few days later and loving it shortly thereafter, she's now absolutely dead set on the name Carl for her little one in utero. I presume I'll not have to explain this to anybody that regularly watches ITV1 at 7pm on weekdays - but having already had remarks (often in gruff imitation Yorkshire accents) when we've been out with our two babies and passers by have asked what their names are - the idea of telling strangers that the three babies in tow are called Matthew, Jimmy and Carl fills me with a mixture of the unsuppressible urge to snigger and profound, face-clawing embarrassment.
Naturally she's perfectly entitled to call her little one whatever she and her boyfriend desire and Carl's a perfectly nice, sensible name otherwise. And I hasten to add I'm being semi-facetious here, but I confess I've been giving it the "ooh no, it's a bit passé, isn't it? I went to school with one who turned out to be a kiddy-fiddler/burglar/BNP official. No... I wouldn't go with that" with increasing vehemence. She doesn't watch the soaps (devil woman) and so the connotations mean nothing to her.
But I can't get past it. These last few days have been almost solely dedicated to putting her off the name Carl. I feel as though I'm impinging on her unarguable right to name as she pleases, purely to prevent hypothetical future embarrassment over nothing on my part.
Undoubtedly I'm pathetic. But AIBU??
(If I am, please don't shout at me! I'm pregnant as well. Any unreasonableness is entirely down to hormone undulation, I've decided.)
