I work four days and I breastfeed morning and night too. The latter has never been a problem unless she is a little late waking up and I need to get a move on to get to work (that is on the days DP takes her to nursery)
She also has breakfast at nursery which helps. I get everything ready the night before, my lunches, clothes, her clothes, nursery things.
Get a slow cooker. That has been a lifesaver for me, I get everything ready the night before and chuck it in in the morning and switch it on.
Do your supermarket shop online in bulk to save irritating dashes to Tesco after work. I don't meal plan for the week but I do get the meat etc out of the freezer the night before to save time.
I bulk cooked loads of DD's food and froze it in pots so I can just whip them out so her meals are sorted.
In an ideal world I would get a cleaner but we can't afford it but that is my dream!!!
I also try to have fun with my DD on my "bonus" day off each week. I save the chores for another time so she feels she has had some quality time with me.
And good luck, if you can be as organised as you can then it isn't so bad. I am far more organised now I am a mum than I ever was before!
