Gosh, of course you are finding it hard....it is all so new. Definitely the online groceries are a must, I did that until DS2 was 4 months, it did take that stress away - and it is a big stress if you have to take all of them shopping. What else can you do to make it easier on yourself - anyway you could get a cleaner in - even once a fortnight to do the bathrooms, vacuum and washing floors / ironing/folding washing....stick with the carrying/co-sleeping if that is making it easier for you and you are getting more sleep....it will get easier when she just gets a little bit older. Do you have access to Aussie Dairy Farmers to deliver milk/bread so at least you have that and don't run out at inconvenient times?
