I did the exact same thing
I named my DS Taylor, at the time I knew of no one else with a child with that name. Well a year or so later, everyone started naming their girls Taylor. Around the 5th grade or so my DS asked why I gave him a girls name. Even a family member (DH's cousin) named their daughter Taylor. She is about 3 years younger than DS (who is now 20). Gets confusing around the holidays
Some names I think are cute for girls are:
Ella (friend just used that one)
Zoe, Zowie or Zoie
Ashlyn
Abby
Best wishes on the little girl!!
