Kitty: The fact that you are trying to learn more about discipline techniques and how to communicate better with Chloe is testament to how great a mummy you are and are trying to me. Its a learning process so I'm glad I can share what works for me though not all may be effective in Chloe's context so its really trial and error.
Oh, and I forgot to mention, after you tell them what is naughty or bad about the action, I reinforce by saying "So can we draw on the wall/spit in future?" and I want to hear him reply himself "No." If not, I explain again. Then at the end, I tell E I love him very much and ask him not to do it again.
ASHM: E is like Ash. Will let everyone snatch his toys and look at me sadly and say "Mummy, boy take Ethan's ball". So I just tell him to take it back, then he walked to the boy and said "Excuse me, ball please." haha...the boy was so surprised that he gave the ball back.
