These are unfortunate and unexpected situations that we need to manage. You said that taking care of such an infant would be difficult without help from other elders at home. If we are to ignite our imagination to such levels, what would one do if there are no elders at home? We need to understand that humans have the intelligence and perseverance to deal with such situations despite feeling helpless. As is said, it is a do-or-die situation. So, the choice is very less, rather, the choice is nil.
'Mastering others is strength. Mastering yourself is true power'. -Lao Tzu
If the mother alone is there, she may take all the care of the kid and she may be able to manage well. But if the only father is alive, it will be very difficult for him to manage the show very well. They don't know how to entertain the kids all the time. Even making them eat food is also a very difficult task for the fathers. They may depend more on the grandparents of the kid. The role of a lady in the house can't be enacted by gents at any cost,

Even this challenging situation would ease
And contrary to the author's belief at times a boy can be more compliant and a girl can be more rebellious so it is not the gender of the child which will create the problem here but the absence of a parent.
One of my friends was raised without a mother and father, a boy has grown well, his mother died when he was in class third and his brother was just three months old, and his father did not take their responsibility any further so both the boys were raised by their unmarried maternal uncle and widowed maternal grandmother and they both grew up just fine.
So a child learns to cope up with the situation as he/she grows up all he/she need is love and nurturing.
