Your brain doesn't stay the same over the course of your whole life, it changes as you do. So you might not be too surprised to find out that a major life event like having a kid can cause some big-time brain changes. Plus, just about every other part of your life changes when you have a kid, so why not your brain too? While you might think that only women's brains are affected by having a kid, that's not actually true. There are also some fascinating changes that happen in men's brains after they have a kid, according to science. These changes range from hormone levels rising and falling, to regions of gray matter actually expanding or shrinking.
Men's brains, like women's brains, even start this changing process before the baby is actually born. Once the baby is born, however, there are even more changes coming. The changes are designed to address the new roles that men need to fill in order to take care of the baby and make sure it's safe and its needs are met. Plus, researchers have found that the more time dads spend with their kids, the more of these brain changes they're affected by. Just conceiving a baby isn't enough to make these changes occur, but spending time around their pregnant partner and connecting with their baby allows for their brains to change in ways necessary to successfully navigate this new life challenge.
