I had my daughter in year 2000, my waist was 45 inches but she weighted 6lb 8oz only. Before I was pregnant, my waist was 23 inches, but because I breast fed my daughter, I came down to 25 - 26 inches within 3 months after given birth. Now I am pregnant with my 2nd child, I was only 12 weeks but the tummy began to stuck out 3 weeks ago.
