I think it's a beautiful name. It sounds very soft and gentle, but kind of haunting.
Winter is my favorite season. I think it could be interpreted as cheesy, but unless you only use it for that reason and not cause you really like the name then I would say it doesn't matter how others might interpret it. Idk if this name is in the running for your little one, but
Natalie and
Winter would be a really sweet sister set.
