I dont do weekend daycare for the simple fact that I have a life and owe time to rest and my own family, my first red flag would be anyone who is willing to do weekend care on a regular basis. just doesn't make sense to me, this is a high paced at times very intense job with the care of all dif personalities and needs if anyone in this job doesn't get a break they are bound to "burn-out", sounds like maybe she wanted to do it for you but later decided it was too much for her to handle. Contrary to what the truth really is, she could have worded her reasons al little dif not to hurt you as she did. Only a few times have I had to let a parent know how I was deeply bothered by childs behavior, or the fact that I was overwhelmed to the point of letting the child go, and in those few situations the parent did not listen to me if I didn't other wise become so honest and blunt, not sure if this is the case, but count your blessings and move on. Not everyone is a good fit for everyone, just continue to look or find family and friends who may better understand the needs of your child on the first place, then you can go to work with less worry. Good Luck!
