I use timeouts over and over and over and removal of toys up on a high shelf if sharing doesn't happen. I tell them they are making me use my angry voice and my angry face and I don't like to do that and ask them to be nice. But when you speak to most children with a louder, firmer voice they usually take notice and know that you are at your limits. You have to be strong and ready to go crazy with doing it again and again for a few months until they understand but it's worth it, believe me! It worked with my own children and it works with my daycare children.

Can you do more food prepping the evening before? Can you put the children at the table with colouring while you cook? Experiment with different methods and find out what works best so your sanity stays intact. Been there dont that! Then, depending on the group I have as turnover happens, the personalities vary and different things work for different groups. You have to figure out what's best for you.
