Nap training

I managed to capture this moment yesterday while little Marcus was napping. 

I have been attempting to nap train him. He tends to wake up after his first sleep cycle and has a hard time soothing himself back for the second cycle. I'm not sure what to do exactly so i try different things, rock him, hold him, walk around with him or put him in the swing. I'm pretty sure I'm confusing him big time. My methods don't work most of the time and the result is a cranky, confused baby. And an exhausted and overly emotional mama. 

Anyway! The rare occasion occurred yesterday that he managed to dose off in the swing. I walked around him on my tiptoes, I hardly even dared to breathe to not wake him up. Then all the sudden he started smiling. Freaky...at first. Then I started gazing at him and he kept smiling, giggling even at times and I just couldn't take my eyes off of him. My heart was full. How can he be so cute and naughty (meaning: not napping) at the same time?
