@Yvette214 Unless you only want to rent them both out to one party of guests, then yes, you need a separate listing for each.
And just a heads-up- not a good idea to use a photo of your child as a hosting profile photo (if it's just a childhood photo of yourself, and you don't actually have children in the home, it's no concern). No problem as far as this forum goes, but you can't be too careful these days about the guests who might be attracted to book with you, if you get my drift.
