I must say that when I have a baby I have learned to just say, 'right, I give up for the next 6 months min' as I can't cope trying to run everything normally with a breast feeding LO in tow. I'm no super-woman and it just puts too much pressure on me (and therefore the whole family) if my expectations are too high! So I just resign myself to getting done what I can and rest assured that we will get back to normal one day!
Hope you fond ways of managing. Sling helped keep me sane!
