A lot of moms feel noticeably calmer with their second baby and then feel guilty about it, like it means they care less. They don't. During your first pregnancy, your brain physically reorganizes itself to prepare for caregiving. By the second pregnancy, your brain does not have to go through that same overhaul because the wiring is already in place. The same changes still happen, just less dramatically. Your brain also recruits new networks for attention and multitasking, which makes sense when you think about what it actually takes to manage two children at once. That calm you feel with subseuqent children is your brain already knowing how to do this.
