Since starting this post we’ve made a more concerted effort to ensure our 8 year old daughter is eating enough. We knew her medication suppressed her appetite some but we hadn’t attributed her mood swings and challenges to lack of food. Since stressing that she eat very regularly (constantly offering food no matter if she says she isn’t hungry) we’ve found she has much greater self control and keeps her mood swings to a minimum. We’ve had good experiences at bedtime too. This has NOT fixed the early waking but she is handling her days much better. Probably stupid of us to overlook such a simple answer, but maybe this will help others.
