can i swap seats with my toddler in business class?

So here’s the situation: my wife, our 3-year-old, and I are planning a big summer trip to Gleneagles in Edinburgh. We’re looking at flying Air France or British Airways, and I had this wild idea—maybe too wild?—about booking two business class seats (for my wife and our toddler) and one economy seat (for me). The catch is, our little one is glued to mom and will want to be with her in business class the whole time. I figured I could just sneak up to the extra business seat once we’re in the air, and then head back to my economy seat for takeoff and landing. But is this actually allowed? I mean, as long as everyone is buckled in their assigned seats for takeoff and landing, does the airline really care if I switch seats mid-flight? Or am I risking a stern talking-to from the flight attendants (or worse)? Has anyone actually tried this? Did the crew let it slide, or did they make you stay in your original seat? I’m honestly torn—on one hand, I want to save a bit of money, but on the other, I don’t want to get in trouble or make things awkward for my family. Would love to hear your real-life stories, especially if you’ve flown with little kids and tried to play musical chairs with your seats. Did it work out, or did you regret not just booking all the same class? #familytravel #airlinetips #travelquestions #parenting #travelstories #Travel
