Since Christmas my nearly 3 year old hasn't slept through the night. She's had a cold and a sickness bug but now she's better, her sleep has gone from bad to worse. Last night she came out of her bed every two hours, and then is up for the day at 6am. Can only think it's separation anxiety as can't see any reason for it. She's so exhausted it's starting to affect her through the day-grumpy, no energy, not wanting to do anything. Her Dad and I are shattered too. Any ideas? Anyone been through the same thing?
