I'm sorry your caregiver didn't try harder to work with you because that's what I like to do with new parents. It takes a lot longer than one week for an 11 month old child to settle into daycare life. They are frightened and confused and it takes weeks and sometimes two or three months before a little one is completely integrated into daycare life in my experience. I wouldn't quit after one week!

I hope you find another caregiver who will work together with you to make your son happy. Good luck with getting some money back - the contract should be fair to both parties.
