Reminds me of my home when I was growing up. Dad spoke seven languages and Mom three. Conversations around the dinner table were always interesting. They may start off in one language, pass through several others before ending with a final. The tradition continued with my sons. All speak at least three languages fluently and are passing on the tradition to the grandchildren who also now speak multiple languages. Kudos to you for passing on the languages and cultures to your sons.
What an advantage for your grandchildren; I do believe this is a wonderful gift to pass on to our children and grandchildren!
Hope you're keeping safe and well over there.Wow that is quite amazing and so interesting @cecicastor! Would sound like a real Babylonian confusion to some, but I can fully understand it as language just comes naturally so one just goes with the flow.
