You are welcome to have some of mine. I have gained around 6kg already (and that is weighing myslef first thing in morning).

If your care provider is not concerned and you are having a balanced diet I wouldn't worry too much. I figure if your diet is healthy your body knows what it is doing, everyone is different and it all depends on how tall you are etc etc.

Good luck and I am sure the weight gain fairy will find you eventually, If you like I will send her your way
