Well, whadda ya know? I learned that Lefty has been training us because we have let him. We think throwing a few treats at him when he wakes me in the middle of the night will shut him up. Nope, it only encourages him to keep doing what works. So last night (on the advice of the internet), I played with him before I went to bed, wore earplugs, & ignored him when he started up in the morning. It worked a treat! He didn't start in till at least 4 & I managed to sleep till almost 5, when he threw a mug at my foot. Ouch! And that was that. I think wearing him out before bed, rather than letting him nap right before bedtime, did the trick. We are taking back control! We are the adults!
