In most of the main series(with the exception of Ruby,Sapphire and Emerald versions), every main character(both ,male and female) only have a mother and she makes up their entire family, no siblings, no father, and no extended family(like cousins, uncles&aunts etc.) or even Grandparents(the mother doesn't even have a mother), why do you think this is? Any theories? 
Not criticizing it or complaining about it, just asking
One of my theories is that the some of the members of Gamefreak grew up with only a mother and as only-child, but then why no extended family?
EDIT: If the mother is only there to play the roles of healing and saving money, what other role do you think she could play?
I have an idea, what if she were to install a healing machine(like the ones used in Pokemon Centers) and an ATM machine for you to deposit and withdraw money in your house, then she goes to train and becomes the Champion of the region when you reach the League, near the end of the game
