Not entirely comfortable posting photos online, but I've been taking weekly side profile pics in the same sport bra (wireless and so comfortable) and yoga pants with a sign underneath indicating the date, how many weeks and the size of the baby along side an object of similar size. I did this my last pregnancy and it was interesting to watch the transition. For my baby shower,as a baby shower game,  I printed a few sets of all the photos (weeks 5 through 35), cut the portion with the sign off and had the guests divide in teams and arrange them in the correct order. The first team to finish with the correct line up won.
