I cant see why he would be teased at all. Its a shame you cant call him your original name but i am totally with you on the pronounciation thing. My daughters called Soraya...said exactly as it is written (so-ray-a) but everywhere we go no matter what she gets called (so-riya) like psoriasis, it drives me Insane and i cant understand why people pronounce it that way.
So anyway kent is lovely. My friends mum told her daughter she hated the name she had picked for her but she stuck to her guns and now she loves it. They will come around and it will be like he couldnt possibly be cakled anything else. Its your choice. Xx
