Silly sleeper

Lately, when I give Alex his bedtime bottle he puts it in his mouth and holds it with his teeth while he crawls to the couch. He climbs onto the couch and then either lays there or sits there to drink it. However, once he gets tired, he is OUT usually. These pictures were taken on three different nights but they're all him sleeping on the couch after having his bottle... Or WHILE having his bottle!
