I am so glad your Rails books are on the way. I have just started with the habit of Obedience, and LDtR has been a huge help to me. I would recommend studying the Obedience section, yes studying it for yourself. Half of obedience is the parent’s doing, as the other ladies have suggested. There is also a chapter at the back on dawdling which I am finding helpful.
The Obedience section has encouraged me to appeal to my DS’s sense of right (do not do this because I said, but because it is right), and his desire to do what is noble. Perhaps that will make more sense when you read the whole section.
We started Obedience September 1st, and I am really spending time understanding Charlotte’s writings on the subject, and doing my part to carryout the authority vested in me. I have already noticed a difference in my son (4yo), and in myself, and look forward to where we will be after concentrated attention to this habit! Be encouraged!! Habits take time, especially when we are correcting poor habits, but the changes will come!
