My sister that 4 yrs younger than me was really small when she was born has always been little and petite too, not me I was the largest baby mom had and now I think on a good day maybe 110 in weight and been that way except when pregnant...then back I go, guess Im just to busy for it to catch me yet but it will someday... we are all different and not like the Osmonds they look like cookie cutter people...LOL
