Niall's morning cocoa is a long-standing tradition that is sorely missed if we (horrors!) run out of milk or somehow forget to make sure it happens. For a long time, I made his cocoa in a sipper cup for him to have on the way to school, and often he'd have another one at night. I think that evolved from his evening bottle of warm milk, that turned into a sipper cup of warm milk, and then switched to cocoa at some point.
Now he relies on this "comfort drink" to give him a warm, yummy start to the day. I often wonder if it will evolve again to a morning latte when he's older or if he'll remain addicted to hot cocoa (like his mom).
