Honestly if you cannot do it anymore then it is OK to just say it isn't working. I had this happen once before and I felt so bad and defeated. I didn't even wait the 2 weeks though, I was done after day 3! I was already the 2nd daycare, the first one only lasted 1 day. The third daycare he was in worked. Some kids just don't work in some settings. Don't feel bad. Think of it this way, you gave it a good shot but you have other kids to think about. How would you feel if your other parents gave notice because of this child? It is always a possibility.

Do what feels best for you - keep going and see how long it takes to get better (eventually it will be it could be weeks or months) or throw in the towel - all up to you.

Good luck with your decision.
