Indulge yourself,
Get your legs waxed, have a facial, prepare meals to freeze in advance, rest, listen to the uninterrupted sound of silence (you will probably miss it), go swimming, go to the cinema, visit your favourite museums, cafes, art galleries and other places that you may be harder to visit in few weeks! Go to the shops and ogle at baby clothes.
Buy an album and put your ultrasound pictures, and any other photos taken during your pregnancy into it, all ready to have baby photos added!
Do yoga or other relaxation techniques, enjoy time to yourself - you will miss it when you have the demands of a baby all day every day!
Soak in bubble baths, spend time with your partner.
Get used to slowing down a bit. Being prepared for a slower pace of life may help you adapt to the first months of your baby's life with greater ease, especially if you are used to a busy, social and working life. Write a diary - start to make or organise birth announcements if you are going to send them out. Just prepare yourself as if you are going to enter a very gentle, slow-paced cocoon with your baby in a few weeeks time, a cocoon that might last a few weeks or even months, but will enable you to get enough sleep and to be alone with your baby without feeling too deprived of your former life!
