Dh sometimes has to leave very early for work. 5am. He will also sometimes get emergency work calls in the very early hours before everyone else wakes up.
I usually set my alarm for 6.15am anyway and wake the dc up by 7.
If dh leaves early he often wakes me up to tell me he's going and if he gets an early call he will stomp around the house talking loudly/shouting on the phone waking me up and I can't get back to sleep.
I think he should go downstairs, close the door and try to be quiet.
