My 6 year old dd is very lively and hyper with a really active imagination. Trying to get her to calm down at bedtime is a constant battle. We do all the usual things bath, story's "quiet time" but she just cannot wind down. Currently, she is going to bed at 8 and only going to sleep at about 9.30-10 It is getting very stressful especially as her little sister is up at 6. Dd wakes about 7. Any ideas of any alternative techniques we could try e.g. Yoga
