I never read the book, but my son has learned that by the time I get to 2 he better be well on his way to correct behavior. We started timeouts with him when he was 1. It took a lot of putting him back in timeout to get him to stay, because it was a game at first. Now he knows to stay there, and if he does test & get up he goes right back & the timer is reset. Different things work for different kids though, and you just have to figure out what works for your son. For mine, time outs & no Diego work for him. My nephew actually needed prized things taken from him. For instance, to stay in bed my sister gave him 2 trucks. Each time he got out of bed, he would lose a truck for the night. Figure out what your son responds to and focus your efforts on that as a form of discipline. Time outs don't work for all kids, but there is something that makes everyone tick. Just make sure that you follow through -- even if it means you're stuck in the house bored all day because you had to take away the pool, the bike, grandma's, the park, etc. Consitancy is key, and the way to create solid behavior is by letting him know that no matter what he does, and where he does it, your reaction is the same. He will test you to make sure he has limits. He needs to know what you expect from him, and will be happier if he knows what is okay. We end every discipline with hugs, kisses, apologies, and I love you.
