Alana Wilcox - baby name discussion

I am due to give birth to our girl soon & have had the name Alana for a long time, call her that, already purchased her name on baby items. It's always been my favourite and preferred spelling for my own daughter. We are in the U.K. and our surname Wilcox is common where we are. However we still have to be cautious with bullies making fun of it........... Unfortunately someone made me aware that kids spell names backwards to tease. Our daughters name backwards has Anal in it!!! I am freaking out. My sister said it's fine i should calm down. I have my heart set on the spelling. Am i being a bad mum if i keep the spelling??? Opinions please :(
