I desperately need help/advice I'm at my wits end. My 5 year old son has always been a big sleeper, often asks me to go to bed at 6.45 and enjoys a good 12/13 hours of uninterrupted sleep every night...until now. 6 days ago he started waking up every half an hour or so after 9pm saying he had tummy ache, we which soon realised wasn't really 'real' but he just can't lie down or keep his head on the pillow for more than a second.he is beside himself with fatigue...as r we. He isn't frightened of anything and doesn't remember anything the morning after. Has anyone else been through this with their child?
