From late afternoon it’s important to remain calm and stick to the bedtime routine, as your dad may pick up on your stress causing him distress. Try to find a balance between your dad not being over-tired while still being tired enough for bed. This might mean experimenting with naptimes. Natural daylight is wonderful for helping to reset a disrupted body-clock, so you should consider simply sitting outdoors or next to a bright window when your dad starts to show signs of agitation or restlessness.
