Hello @MelodyM and a very warm welcome to the Community Forum 
There are sitters on here who range from sitting maybe once a year to others who sit all year round so you are certainly not alone in this situation.
For reference as a member and once your listing is completed you can also add your TrustedHousesitters profile on to your Forum profile by following the attached link, should you wish. This will then enable others to offer you helpful advice and feedback.
Also, remember you can use the spyglass symbol at the top of the page next to the TrustedHousesitters logo and search for any questions that you may have as they have most likely already been answered on here and of course if not then please just ask!
