I hate to say I feel it is somewhat true. I have grandchildren already so have some experience.
First, our family stresses Mom strongly. Each child encouraged to rely on Mom. Period. And us Moms are dedicated. Period.
Too many distractions for both Mom and child where their need for each other can be diminished due to so much other available social contact. Family seems to be secondary or in the background. They text each other in the same house for goodness sakes. That can't develop relationships.
Loving a child and being Mom are two different things.
