Pre-preg weight: 135-140
Final preg weight: 178
24 hours postprtum (on hospital scale this morning so it's a "new" scale): 162
I seem to drift back to within 10lbs of my pre-preg weight without effort over the first 9 months or so and then stay there. Around a year I focus diet/exercise on dropping those last lbs and so far I've been roughly ten lbs below my pre-preg weight by the babe's first bitrthday.
But as for fitting into prepreg clothes? It never happens!

Even when the scale says I'm back to "normal"... I'm not!
