I had the same thing happen too. I filled my time with extra cleaning and scrapbooking. The scrapbooking was certainly more fun that the cleaning and it was so nice to get all of baby's things in order. I have scrapbooked all of the baby shower cards and photos, ultrasounds, and my maternity pictures. Have fun with it and enjoy your time before baby arrives. I even planned a few trips (to the beach, an outing with hubby, things we can't do later). It helps to pass the time. :)
You can come over my house, there is PLENTY to be done! haha I haven't started a single thing yet, haven't even bought a pack of diapers!! I am almost 30 weeks, but bedrest has me confined! grrr. In 6 weeks, I will be a mad woman cleaning and getting things in order, I'm afraid I won't have enough time!! LOL Plan a trip like a little getaway before baby arrives, or just sit back and relax. With my first pregnancy, I had everything done by the 3rd trimester, so I just focused on exercising, stretching, and just relaxing, renting movies or finding another good book to read. Also, if you like to cook, plan ahead and make some meals one day and put them in the freezer so when baby does arrive, you will have some meals ready to be popped into the oven, no work! :)
