It is normal for children to be cared for by many adults throughout the day, from birth - be they older relatives or simply members of the community. It is abnormal for one person to have to deal with all of their energy and issues. It is normal for children to wander and play and experience a wide and varied world. It is abnormal for them to be kept in a small, unchanging indoor space. It is normal for new parents, especially new mothers, to be intensely supported by their community. It is abnormal for them to be left alone unsupported. It is normal for homemakers to accomplish their daily tasks communally and to be active in their communities. It is abnormal for them to endure years of social isolation, primarily spending time with their children.
I am not sure what a healthy pattern for family support and child rearing looks like in this society, but I think public support for young child care, better connections with older relatives and neighbors for light child care, and light or part time but potentially meaningful work and social connections for parents is a lot closer to normalcy than the current locked together in isolation suffering silently pretending to be happy wondering why you're the only one struggling model we have now. The current model is insane and it is a testament to our toughness as human beings that we all try so hard to make it work and survive as well as we do.
