I'm due very close to a close family member. I know I'm having a girl but she doesn't know what she's having yet. When I saw her last she told me her favourite boys name which is the male version of our favourite girls name. She's due a month before me. Is it acceptable/weird to call my DD the name we like if she has already called her son (if she had a boy) the male name. They are identical names apart from the addition of two letters. Think George/Georgie, Charles/Charlie, Joe/Jonie
