Let's create a list of pro's and cons! I may have the option of either come fall. I've had three people offer to be my nanny when they heard I was looking for daycare and they're all willing to work with me regarding pay.

Nanny:
- Cobi can easily keep his nap schedule
- one-on-one care
- eats our healthy food at home
- usually more $$
- can go out for field trips
- nanny can possibly help with light clean up during naps
- in home, so it's more comfortable
- less likely to get sick

Day care:
- more opportunities for socialization
- along with socialization, learning to share, get along with others, "make friends"
- usually cheaper than a nanny
- often there is structure/routine
- sometimes more activities or "program" with learning opportunities
- pay is per day/week so if I need an extra hour it doesn't matter (assuming he's there 8 hours a day)

What else? What did/would you choose?
