Aww, congrats mama! For girl names starting with R and H, a few of us in our mum group love Rosalie paired with Hannah, or Ruby with Hope, they sound so sweet together and hindi masyadong common! Pero honestly, it really depends sa family names ninyo and kung ano ang feel ng combination, maganda din ang Raven with Hazel, or Raegan with Henriette if you want something more unique. What's your last name? Sometimes na-inspire kami ng how it flows together!
