Coincidently I caught a supernanny drop in programme on exactly this topic. She was chatting to a couple who were concerned about eyelid and lashes being pulled. Her recommendation to them was as advised above - it is a phase. Don't draw unnecessary attention to it, it will only encourage the behaviour when in need of a bit of attention. It isn't caused by any deep psychological need and will stop. I would definately free the doll from the cupboard. Understand concerns through - my son 'stretched' his eyes open wide. Apparently a tick, and everyone said it would pass. We had his eyes tested, no problem visited the dr's just in case something more serious, no problem. It had been going on for about 18months/2 years then suddenly stopped. Bizarre! Just another one of those things that children do to test us!
