I have taken a few courses provided by ASCY in Hamilton which have been very informative. I also agree that the "make and take" workshops are the best because you leave with something that you can use in your daycare.
I am also part of a few networking groups in my area and have found them to be the best learning for me. Talking with other providers in my area who have been providing care or 5,10, 15 and evening 20 years. They have some great ideas about every aspect of your daycare. Highly recommended!!!
