Would it have been allowed by the captain for the parent to give consent to a neighbouring volunteering pax to oversee 2 children for 5 minutes. Or would she have had to cross her legs for 2 hours.
A female friend of mine did just this for a woman on flight a year or two ago. Mother and toddler went to the loo and she volunteered to look after the baby which promptly puked up all over her. Perhaps Easy have a point after all
