So tired

Parental tiredness is a special kind of tiredness, a slow, creeping, cumulative thing that gradually wares you down over the weeks and months until you can barely keep you eyes open. No amount of all-nighters when you are young prepares you for it.  And just when you think that you have everything under control, it comes back to hit you.
Both Jo and I are going through an on-our-knees-tired phase at the moment. It's a combination of us both having full-on, stressful and emotionally draining jobs, an office that is miles from home and the fact that Sam has started waking up in the night again and then very early in the morning so we never get a chance to lie in.
There is just no time to catch up with yourself and there seems very few opportunities to take a day off either,which means that we are like walking zombies at the moment. And this is with one kid.....
I am sure we suffer more than other couples where one of them is either at home or in a relatively relaxed job. There doesn't seem a great deal we can do apart from try and get into bed early but I find that difficult to do after a stressful day when I really need time to chill out for a bit rather than get straight into bed.
Sam is beautiful and amazing as usual. But he is at an age where he really demands constant attention. I think that we are good at sharing the load but it does mean that we are both as exhausted as each other. Cue short tempers etc. Frustrating.......
