Daycare Pros
More respect from friends and family. If you work in the 2s room or with older kids you get the title teacher or assistant teacher. People respect this far more than telling people you are a nanny. Pro
No housework or domestic tasks. Pro
Sometimes better benefits if its a center in a large company. Sometimes benefits are terrible. Pro/Con
Calling out sick is less of a concern. Pro
You get a real lunch break. Pro
More security. Unless you are late or call out all the time, you can keep your position year after year. Nannies jobs come to end anywhere from 1-4 years. Pro
More encouragement to get certifications and education. They want their staff to have child development and child care certifications, CPR, and some will pay, provide or even require that you continue your education. As a nanny it only makes a difference when searching for a new job. Pro.
Access to lots of materials, toys, art supplies. Pro.
Nanny Pros
Better pay and you get paid when you don't work. In daycare, hourly means hourly. No leaving early and getting paid. Daycare won't take an extra week off and give you pay. Pro
Lots of downtime and time to run your own errands. The less housework you negotiate the longer you get to do whatever you want. Huge Pro
Run your own errands. Pro
Meet up with other nannies that you choose. In daycare you are stuck socializing with your co-workers only. Pro
Free food. Most families will provide you with food for breakfast, lunch and snack. Saves a lot on groceries. Pro
Much less work. In daycare, you are working all day other than your scheduled lunch and breaks. 1-2 kids is a breeze after working in a daycare. Pro.
Freedom. As a nanny you get to do what you want to do. If you don't like being cold, the kids stay inside. If you like to walk around malls, the kids go to a mall. If you like music,the kids dance to music. Huge Pro.
If you get luck and find a family that takes lots of vacation and does guaranteed pay you get weeks and weeks of paid time off.
So basically what you think is that as a nanny you can try to do as little work as possible, get as much PTO as possible, and do whatever you want to do, including running your own errands and making daily plans around YOUR needs and desires.
Please, please stick to working in daycare. You seem to need the supervision, and no child deserves a "nanny" like you. You sound very self-centered and incapable of planning a day as a nanny that is focused on the needs and desires of the children entrusted to you.
P.S. Yes, working in a day care is hard. But so is working as a nanny if you do it correctly and responsibly.
