Stupid question : where is the father supposed to learn ?
It does have to be said that the rest of the talk/instruction/help was very focussed upon the mother (as you'd expect). I remember that all the meals we were provided with had labels:
* The meals for the mother had her full-name on them.
* The meals for me just said "father".
The answer is: you eventually figure it out after lots of panicking :P
