DD has been under the weather last few days with a raised temp. It was last high at about 11am today and although a bit grumpy she has been fine for the rest of the day. The problem starts when she lays down to go to sleep. For 3 attempts at naps today and at bedtime now she falls asleep for a minute or two (well her eyes are closed) but then suddenly she jumps out of her skin, sits bolt upright and crys. What could be causing this? I took her to the docs today - he checked her ears and chest and said they were fine.
