@Sam4784 Airbnbs aren't hotels. They are people's private homes. Some are set up to accommodate families and some aren't. Some aren't safe at all for little ones. And Airbnb's designation of "infants" as 0-2 is a huge problem. A babe in arms, not yet mobile on their own, is a whole different kettle of fish than a 2 year old running around, climbing up on things, scribbling with markers.
You may be a responsible parent, but many are not. A hotel has your credit card number and charges guests for damages. That isn't what hosts can do on Airbnb. If the guest refuses to pay, which many do, it's a long convoluted process for hosts to try to get Airbnb to cover the damages.
Hosts have had toddlers scribble on the walls and bedding with indelible ink, find cheerios strewn all over the house, food ground into the carpets and upholstery.
Not accepting children in a listing that isn't suitable for them has nothing to do with being "professional".
BTW, I raised 3 kids and have 6 grandchildren. I like kids just fine, but I did not ever assume I could take them everywhere.
