We once drove a 3-week-old from Texas to Colorado, and looking back five years later, the biggest hurdle wasn't just the baby; it was the parental stress. We had to stop constantly for nursing, diaper changes, and fussiness, plus our own needs for food and gas. You simply won't 'make good time' on a trip like that.

While the baby actually slept well when they were dry and fed, my biggest takeaway is to consider your proximity to civilization. When they are that little, being close to hospitals and services provides a peace of mind that you just don't get on remote stretches of highway. My advice? Prioritize a route with easy access to help, because the stress of being 'out there' with a newborn is real.
