Sleep interrupted every night without fail. Little boy stirs in his bedroom and comes to his door steadily increasing his cries. We have started to be firm with our voices to make him understand he's not to get up but it's still a struggle. My friend is expecting his third and he's ready got two toddlers, I can't imagine how that's going to operate.
I feel fine through the day while imbibing yucky coffee but once bedtime approaches my body switches off. The last couple of evenings I have been made to go to bed before properly tired because when your wife goes to bed 
Nine times out of ten you HAVE to go to bed at the same time. But yes sleep is being interrupted and it's an important commodity.
