Baby name thoughts?

Kelly • Mommy of 6, should we make it 7?!?!

My husband left a peice of paper out last night and he wrote

Iris Sara McSween

Iris was my moms middle name and we tossed the idea of it around a few times. Sara is his Grandmother's name and his sister....

Do you think it flows well, I feel like it's kinda weird on the tongue saying Iris Sara, both 4 letters but the whole name together sounds fine. And in all reality wont be using middle name much except for documents. Thoughts?
