Hii @Viviana196 , Unfortunately, Airbnb doesn't count them as a paying guest on the reservation until they are 3. You may be able to add to your House Rules that you DO charge for Every Body that is in your listing, Age notwithstanding. Many hosts do but I have no idea whether or not they are successful in collecting for 2 and under. I don't charge for 2 and under at this time, my listing is super family friendly but i do feel that the "Infant" age should be 1 year or less, not 2 years or  less. A 2 year old is NOT an infant.
