My DD is 3.3 yrs old and dropped her daytime nap probably coming up to a year ago and has always been fine with this. She sleeps 7ish till 6ish with normally one short wake up for a lost teddy or covers at some point during the night. Recently she just seems to be exhausted all the time though. Very tearful and clumsy with it. She has recently started pre-school four mornings a week so I know that has an effect but it seems to be getting worse not better. I can't give her a daytime sleep as it hugely impacts on her nighttime sleep so other than giving me an easier afternoon is counter productive. Does anyone have any ideas on why this might be happening and any tips to give her more energy? Maybe ideas about diet? Thanks
