Forgot to mention that for me; so far the toughest thing about being pregnant is the diapers! :) You know how it's just a little bit icky-er when it's someone else's kid.... lol
And I had it pretty rough the first little while (well, the first 17 or 18 weeks unfortunately). Another reason I told the parents a little earlier, so that hopefully there was some understanding if I was looking a little more drawn-out than usual.
