There are some commercial operations that will seize on this research as proof women are incompetent as mothers generally and they need the advice and help from a third party paid advisor or worker who took some courses.
However it is equally logical to notice that the economy is tilted to devalue care of children so that mothers can't get funding when they give birth, suffer income loss when they are home with a newborn and lose place in the corporate ladder or in pension if they devote time to the child. Then we have also created a tax system where grandmas also are unable to afford to be home and are pressured to earn so they too are unavailable to rush across the city or country to help out with grandchildren. It does not mean we moms and grandmas are incompetent at all , or unwilling. It means the tax system in the male paradigm that only values paid work, successfully devalued our care roles pretty thoroughly and removed from us most options. The real answer is to fund a birth bonus, universal maternity benefit for at least one year, and universal funding per child that flows with the child till age 18. Then grandmas, moms, dads, sitters, nannies, daycare workers, could all provide care as the child needed and the parents wished.
