Wow Libby, this is very exciting! I want to be taller too!
I can understand feeling worried about losing the two inches in height after a pregnancy. My mother began early stages of osteoporosis in her forties so I'm watching this pretty close for myself. I don't have an answer for you though. Maybe you were measured incorrectly the first time, two inches seems like a lot. Maybe with the weightloss, 63lbs, your body has adjusted with better posture which may account for an extra inch. Don't know. But congratulations anyway! Wow, taller and leaner! 63lbs is just awesome!
I love reading about all the great things weight training can do for us after I just had a good workout.
