How do you teach a child to fall asleep?

[HairyMaclary]

My DS2 is a terrible sleeper, he's now 14 months old and cannot fall asleep by himself. I'm still bfing but even that doesn't always send him off. In desperation last night at 11.45pm DH took him for a drive, it took him 40 mins to even close his eyes! Does anyone have any suggestions to help, we've tried sitting with him and everything we can think of, and are now getting desperate. How do you teach a child to fall asleep when they seem unable to 'switch of'. Please help!
