I agree about the competition thing but sometimes when you are absolutely shattered and your DP/H is moaning about it too, despite having much more sleep it can be enraging.
At the moment, I am 33 weeks pregnant, have been suffering with chronic heartburn which isn't relieved with any medication. I have two DC (20 months and 3.7), work 30 hours in 3 days with a two hour daily commute. I also take the DC on public transport to nursery opposite my work for those days.
By contrast, DP works from bed home every day. His work is mostly online/by telephone so he doesn't even need to get dressed.
He sleeps in the spare bedroom usually as he doesn't like being disturbed (which is fine by me as the DC come in bed with me and there's no room!)
I get up with the DC every morning except Sundays because I'm now programmed for an early start.
He still moans about being more tired.
If I mention being tired he immediately counters with how tired he is or how little sleep he has had. He did the same when I was EBFing both DC.
In fact, last night he went to bed an hour before me and it's still me who is up today.
It's fucking annoying.
I'm currently contemplating unleashing the DC on him while I have a shower.
