I agree with Fiona too!!! A lot does depend on your starting weight and many women who are generally quite slim do seem to "need" to put on more weight than ladies who are larger to begin with. Having said that, for my first pg I put on 20kg and ended up being 100kg by the time DD was born! The weight was NOT easy to shift, even though I breastfed for 7 months (until DD rejected the breast) I then had to make a very big effort to lose 28kg over 5 1/2 months. This time I am 24 weeks, have put on 4kg and weigh 75kg - much healthier for me! The important thing is not to "diet" but just to eat healthily - try to cut out the empty calories (junkfood, sugary stuff etc) because they have very litle nutritional value, no vitamins etc for bubs, and just eat fresh, unprocessed food that will nourish you and bubs. That combined with light exercise will mean that you stay healthy, and if you do put on a lot of weight it's because your body needed to. My biggest problem was i made excuses for myself to eat junk - "oh well, I'm pregnant" or "I can lose it later" etc and I still have done that a bit this time (I had KFC for lunch and am sorry I did now cause its sitting like a lump in the bottom of my stomach!) but have tried not to go too berserk. Anyway, that's my 2 cents worth! Hope it helps!
