Ethan’s been sleeping on his side recently. That’s how his daddy sleeps and now he sleeps like that too. It’s a thing he does. He has a “thing.” My baby is developing traits and exhibiting behaviour that sets him apart and makes him an individual. Certainly sleeping on one’s side is not unique to my kid, but how many kids sleep on their side and also burrow their head in my chest after repeatedly hopping up and down on my lap while also beaming with a wide-eyed smile? None, just mine.
