Our beardie, Shen, is about four months old. And he will sleep when his lights turn off at night. But, he wakes up at the smallest sound or light, so recently, within the last month, I've started to wait for his lights to go out and then I'll put him in his blankie. While my boyfriend thinks its dumb and pointless (in his opinion Shen should be left alone and never touched or handled) Shen falls asleep almost immediately when I tuck him in at night, and then we won't see him till his light comes on the next morning.
My boyfriend has started to see that it's fine to take Shen out and play with him during the day. Hopefully he'll ease up on the blankie issue and stop taking it out and hiding it from me.
