I want honest opinions, please.

So I'm set on a boy name, but since I told my sister the girl name we have picked out for our second child, and she said she didn't really like it, it changed my feelings towards it. Probably because I'm pregnant and emotional, lol.

The girl name we have picked out is: Avynn Aline. Pronounced Ay-ven Ale-een .

Aline was my husband's Mother's middle name, whom passed away, so it has so much meaning.

I won't get my feelings hurt if someone in here states their opinion because I don't personally know anyone in here. I absolutely love unique names, so Avynn really caught my eye. Do you think the name flows together, or does it not sound like it should go together??
