I have heard from someone else that it can become an addictive sleep primer.
The other tip I forgot, is that they need to be full of food. If they are very tired/irritable and not going down, offer their 3 favourite foods + some milk. After eating their fill, this should trigger a whole bunch of sleepiness.
Ayyy, love Brad Sucks! Listened to this tune 50 or 100 times. :D
Up there with other nice CC artists like Grace Valhalla, or Professor Kliq.
