Scarlet it is normal to be that hectic in these early weeks, is there anyway you can include Ds more like having special books or toys, or cuddling him at the same time? I think possibly DH seeming less bonded could be due to a crazy work schedule?
Is there any bf support groups in your area, where you could be checked to see if there is a reason she is feeding frequently? These groups can be so helpful generally too :) You can look it up here
It would be a shame to stop when you have had struggles overcome them and things are going well as it is so good for both of you to breastfeed. Pomme did have a wobble so hopefully she will have some sage advice on this :)
I find getting out really good for making me feel better, I have a double as long distances are too far for DD. A buggy board would have been fine but they just seem to be a nightmare and I was concerned I would still have backache .etc after my rubbish pregnancy so double it was! If you buy a second hand p&t or something you shouldn't lose any money when you come to sell, some say consider it a rental. 
How are you feeling in yourself generally? As you seem frustrated at things around you rather than specifically the feeding.
Practical wise, In the earlier days, I was boiling eggs and pasta in the evening when I had help, for the next day so that I just need to chop some veggies up for pasta salad or peel an egg for a snack for DD. I also buy regularly fresh pasta and gnocchi as it takes 3mins for them to cook and you can put pesto through it. Also fruit is good snacking material :) And I invested in a tesco value toastie machine for something quick and hot and now DD is addicted to these!
On hot days your milk does change so that baby doesn't get dehydrated, so that is why your extra thirsty Biscuits suncream is not allowed before 6 months, can't remember why though..
Jaggy this is the best nursing top for summer ever other patterns too :)
Too H is having his 1st jabs this Fri too, I just think he has had longer to develop his body so he won't be poorly because of them..
Wants you are at weight management group already?! Blimey, I am starting it next week and my GP was concerned I had 'unrealistic expectations' as it takes 9 months to put weight on so should take 9 months to come off... I said I have put three stone on having the two children and weigh more than my husband, so something needs to happen! lol
