Thank you pikz and fruit. Amazing what a full nights sleep can do. I feel human, and ready to face whatever is thrown at me. However not what DP throws at me. He's in the bad books, and tempers are very frayed.
When I went to bed last night, he clearly can't manage to tidy up and sort things without me instructing him. He left all O's clothes strewn about the house, wires trailing everywhere so I had to run around and move them all plus all the small bits off the floor before I could put O down this morning. He'd left the kitchen an absolute state, mop bucket with bleach in the middle of the floor
shit all over the sides, dirt everywhere, oven filthy. And the worst thing, as he got ready this morning, I heard him put the ice packs back in the freezer. I had a funny feeling that he put the bottles - made at 7pm last night - in the fridge. At 7am this morning. 
I tested my theory by heating a bottle at the normal 45 seconds. It was piping hot. 45 secs puts it at room temp.
So I rang him, and he laughed and admitted it. 
I can't even tell you how mad it made me. Sure you can guess! Okay, so you make a mistake, but to put them in the fridge and then make pathetic excuses as to why the fuck you didn't tell me, and risk me giving them to O and making him ill? What the fuck is wrong with him? Why would he do something so fucking stupid?
So I had to shovel breakfast in O first, while trying to make bottles. 
Luckily after the initial screaming because he saw the bottle, he calmed down. And when he did finally get a feed at 8.45, he fell asleep. Thank fuck no rocking required!
Yesterday he had a total of 35 minutes sleep. ALL DAY. He's now having 2-3.5 hours sleep across the day, occasionally longer, occasionally shorter. But 35 minutes is unheard of.
Anyway. It's a new day, DP can fuck off, and I am not tired. So I can deal with everything life wants to throw at me.
Shall reply to fred
