We use cloth diapers. I do have an emergency stash of disposables for Hurricane season. We typically bring our cloth diapers when we travel or go camping. My two youngest aren't in day care so I dont' have that issue. When my oldest was a baby and started day care at 1 year of age, her day care required disposable and so she used cloth at home and disposables at day care.
Do what feels best for you. It is intimidatng and overwhelming once you decide to use cloth because, like slings, there are so many options available and what works for one person might not be the best for another. Good luck in deciding what to use.
