How do you redirect your anger?

How are we redirecting our anger/annoyance at our other halves because I'm on the absolute verge of blowing up or crying.
It's just a bunch of little things I think that have added up and I keep apologizing for being moody but then more things happen, at this point I could honestly take the baby and the dog and go.
For example our baby has silent reflux and has had colic, I ask OH last week if he's putting the water in and then the formula because when I looked at some of the bottles he made they were just over 120ml instead of 150ml So i asked how many scoops were in it, he said 5, I said you've not out enough water in for 5, he said he had. Then today I've been on my way out to do the weekly shop, he's putting formula in the bottles before the water, so I've said you're not supposed to do it that way, he said says who, well me, Google, the midwife, the health visitor, the fucking back of box, he chucked the formula back in the box in a huff and then said are you going now because your doing my head in I've only just got in from work - 1) do it properly 2) I asked him if he could not spend 45 minutes upstairs when he comes home from work because I needed to go and pick something up at 6:30 and he got in around 6:10 normally he comes down around 7pm so he was already in a mood. I told him that's probably why the baby is crying in pain if he's not making the bottles correctly.
Then we're running out of formula and forgot it from the shop so I said I think it'll last til tomorrow he said he dropped some bottles because he was doing it with one hand - I do everything with one hand. I think I've been the loo once without the baby, I eat my food with one hand even though we normally eat together, there isn't much I don't do one handed including making the bottles.
Even when he's off work I feel like he might as well be at work, I don't think we've had a conversation longer than 2 minutes for about a week, we've got a meal booked for Saturday and I just want to cancel it, because I no I'm going to be the one who eats one handed and he'll say just put the baby down - then the baby will cry and then everyone looks at me. I don't think he's once tried to soothe the baby off to sleep, he's got no issues staying up past midnight when the baby comes to bed with me but when he's got the baby it's a different story, it'll be midnight on the dot and the baby will be handed to me whether I'm asleep or not, like tonight baby is 9 weeks so trying to get him into a routine so put him to bed upstairs he was crying so I went up, soothed him and came back down, then again crying I'm in the middle of doing something he's made no attempt to get up so I've got up again. 3rd time baby crying, not even a flinch from him.
Over the last few weeks he's been having the baby until midnight and bringing up but over a week he forgot to bring something up with him, once it was hot water so I've got a screaming baby but I've got to wait for the kettle to boil, then it was wipes not helpful when there's an poop explosion at 2am and just things like that.

So sorry for the rant, but I just feel like he's doing it wrong on purpose so he doesn't have to do it, get a grip.
