My LO has a pattern of starting to feel sick in the afternoons before dinner- lightheaded, despondent, crying, afraid, may or may not complain of pain or be agitated. I have read that it’s important to remain calm and remember that she can’t help it, and to maintain a routine that helps her feel safe and secure. Any other ideas? Going to bed seems to be the only solution, and when she wakes up she is usually her normal bright eyed self. The episodes are very upsetting to her (and to me).
A geriatric psychiatrist may be a good person to add to your team.
As for feeling sick before dinner, does your love one have a snack between lunch and dinner. If not, she could be having a drop in blood surgar. I always need to eat something around 3pm. Usually pop corn, small pastry, a hand full of peanuts.
