@Branka-and-Silvia0, thanks! Yes, it can be very helpful to know if children are coming. In a perfect world, a guest would book with an appropriate message such as, "Hey, my husband and I are bringing our 5-year-old daughter for a long weekend." Of course, many and probably most will not.
In my space, I have many hazards for children, including a hot wood stove and many stairs and quite high deck areas, which present fall hazards, so I like to know if children are coming. I request in several places on my listing to alert me if children are coming, but of course, as we know many do not read the listing!
Will keep an extra eye on this new 'improvement'.
