Young girl (maybe 2 1/2) comes down the aisle and stops. Looks at me, I smile. She then clambers onto empty seat (armrest was up), proceeds to walk over my legs to get a view out the window. My hands went around her waist to steady her. A few minutes later FA comes down the aisle looking. Gives me a smile - I gave her my help expression. Mum arrived shortly thereafter.
The tragic thing about this kind human gesture is that if it had been in the UK (I'm assuming it wasn't?) you'd probably have been labelled a pervert by some interfering busybody.
