I need input, having real internal struggle over my baby girl's name. Cara is her first name. for middle names I was thinking Lyn (for my sister) and Renee (mine and my mothers middle name). but my best friends mom passed away from cancer recently. I'm due on her birthday. she was like a mom to me. (taught me to shave my legs and pluck my eye brows and dressed me for my first school dance etc) part of me wants to include her name in my babies name in memory of her. her first name was Dorothy and middle name Gail. I was thinking Cara Dorothy Renee but I still love Cara Lyn Renee for her. I know it would have meant a lot to Dorothy for her "granddaughter" to be named for her... I don't know what to do.
