Why is it over the top??? It is definately acheiveable. 10 and a half stone is acheiveable dont sell yourself short! Are you saying it because you dont think you can do it or because you think its too low?
Thats ok I thought you were doubting yourself. See how you feel at 11.5lb. Remember she may hold her weight in different places to you so you may feel good at the same weight but then you may feel you'd like to go a little lower, so see how you feel. 11.5lb may be just perfect for you. I cant wait to see!
