Sorry, but no picture of this. Got upgrade on MSP to SEA flight into 1B. Woman with pre-toddler age infant sits in 1A. After take-off I doze, but get awakened by FA leaning over me to tell the woman in 1A “No, that’s against the rules. You can’t do that”. I look over to see she is barefoot with her feet on the bulkhead. I think “Wow, that’s pretty aggressive by the FA. Never seen anyone called out for feet on the bulkhead”, but then I notice why the FA was chewing her out - the woman has laid her sleeping child down on the floor. How many ways was that a bad idea – filthy floor, usually pretty cold and any turbulence and the kid goes flying. Probably safer to put her in the overhead…
