It exists but it is usually pretty slim. Usually works out to be 2 weeks a year or something, which if you have a family and go to regular doctors appointments as advised, by the time your done... No more time for an actual vacation.

The average person is supposed to go to the dentist twice a year, the doctor once, a dermatologist once, the gynecologist once. If Anything is wrong, like a cavity.. you need another trip. So we are up to at least 6 half days off there.

So let's say another 3 for the kids. 2 dentists, and 1 physical whether it be for general health or for sports. (Vaccinations? All that jazz). Now any parent would know we are undershooting these numbers by a lot, as we haven't talked at all about a kid getting sick yet.

Parents/Grandparents need a ride to the doctor once or twice, assuming you divy it out over multiple kids. Maybe one breaks a hip and needs physical therapy your fucked.

Note none of this has included a single day that is ever considered to be a vacation, just half days and rushing around and trying to get back to work.

If somehow you get through all of this, what many people do is take their last couple hours of free time to fly to where their in laws are to celebrate Christmas or some shit. Which is why there is so much animosity surrounding the holidays. It is the last time that someone may have to spend to relax, and they end up spending it with others who all don't want to be making large extravagant meals, putting up and taking down decorations nor spending money they didn't have in the first place, to waste time figuring out some gift they feel obligated to give to someone that yes they care about, but really is obstructing their last few moments where they could actually take a vacation and relax.
