Meredith, like you I am about 160 - 165 cms tall and weighed about 50kgs pre pg. First pg I put on heaps - 16 kgs all up I think but lost it all very easily with bf. In fact, I kept losing weight bf right up until conceiving. This pg I bf for the first 4 months and put on only 4kgs in all that time. Then DS self-weaned and I have now put on another 2 or 3 kgs. Not nearly as much as the first time around. Funny, first pg I was worried I was putting on too much, this time I've been worried about not enough.

But if ob/midwife is not worried, don't worry. It appears that there is a very wide range in acceptable weight gains.
