Lay down some deep freezer dinners! The ability to pull out a casserole and heat it in the oven will be a godsend some evenings!

Make sure your curtains all block out the light ok cos there will be times when you want daytime darkness for sleeping!

I agree with big clutter clean out - you accumulate so much stuff when Bubba arrives, it will all need to go somewhere. Also try to create a space for the unfolded clean washing to live so it's not sitting in the loungeroom all the time!

And lastly, but most importantly - schedule some quality time with DH, good girl friends, and by your lonesome. Time is the most precious commodity with a newborn!
