Research shows a baby's brain can double in size by the first year, and by the child's fifth birthday 95 percent of their total brain growth has taken place.
What we now know, thanks to the work of Dr. Sarah Watamura, Dr. Pilyoung Kim, Tiffany Phu, and Andrew Erhart from the University of Denver in “Two Open Windows: Part II,” is that adults transitioning to parenthood are also experiencing brain bursts.
In fact, all caregivers, regardless of biological connection to their baby, experience brain developments as they become parents, like learning if a baby’s cry means they are hungry or needs a diaper change.
The science now calls us to extend proven supports like home visits and stress-reduction classes to fathers, adoptive parents, and other adults who take on the primary parenting responsibilities for a young child.
It is the act of transitioning to parenthood, whether a biological parent or not, that opens a time-limited window where both new parent and baby are especially receptive to being shaped by their environments.
It is a window of opportunity if handled respectfully and intentionally, where we can support and set families on a path to health and well-being.
Doing this for parents, caregivers and babies together in this early window will pay off in the short-term by helping parents and children cope with stress and, in the long-term, by setting children on a path to be successful in school and later in life.
What is clear is that we need to support all adults who are becoming parents. Here are three things policymakers, practitioners, and businesses can embrace to support families in growing stronger and more resilient:
• Time for a Mom Plus Plan. Our approach must be both, and not either/or. Let’s apply the research findings and create robust, inclusive policies and supports that double-down on moms as well as bring in fathers, grandparents, adoptive, and nonbiological parents too.
• Modernize antiquated workplace mindsets and polices, include all parenting adults. Fathers, aunties, and grandparent guardians experience the same brain changes as they transition to parenting but often with less support.
Nonbiological parents include adoptive and same-sex couples as well. Too many workplaces offer maternal leave rather than parental leave, and many community programs are geared only to moms.
We need to enable anyone in the parenting role to spend significant time in the early years with their children as it assists with the brain development most beneficial to both.
As a society, we can learn a lot from African American fathers who on average spend more time with their children. Black fathers (70 percent) were most likely to have bathed, dressed, diapered, or helped their children use the toilet every day compared with white (60 percent) and Hispanic fathers (45 percent), a model all fathers should follow.
• Find ways to lower stress, particularly toxic stress permanently, and especially as we address the impacts of both COVID and racism. Our top job is to consider how to prevent or minimize toxic stress that can undermine parenting.
Toxic stress is more than regular stress. It is stress that happens in the context of low support. Combatting stressors like racism or a global pandemic also take a toll.
When new parents experience toxic stress, it taxes the neurological system needed to figure out a baby’s needs. Supporting new parents, especially those who have experienced trauma, will give them the wherewithal to buffer their children from stress and navigate tough situations.
We need to align our mental health systems in more equitable ways, including mental health screening and support to process trauma for all transitioning to parenthood.
Embracing a two-generation approach for infants and parents and leveraging the emerging brain science is a game changer in how we design services, supports, and care for families during this critical moment of transitioning to parenthood.
The science shows why common-sense policies like equitable paid family leave for all families, and early supports like home visits that connect new parents to new learning or education opportunities will widen the two open windows parenthood unlocks.
Parenthood changes everything, including your brain. It’s a “no-brainer” and an opportunity we don’t want to miss.
