Question about awkward hugs (with family)

It all started two years ago, when I first went to Europe to visit some family. I met an uncle for the first time while there. At the airport, we shook hands. When leaving the country (a few weeks later), I think he was going for a handshake, but instead I gave him a hug, which felt super awkward. In a few days, I'm going back over there, and I really don't want to make it awkward when I see him and my other family again. I hope I don't sound crazy (most likely overthinking this a lot), but do any of you have tips on what I could do when I get there to avoid awkwardness? Thank you for any advice you may have!
