Apart from Kim K - I've noticed - or rather its been brought to my attention - how little weight many of the pregnant ladies in the public eye put on. A friend of mine who I met for coffee and who knows me well posed this question to me. I've had quite bad morning sickness and heartburn this pregnancy (DD2) -but have managed to stay active and eat heathily (tbh - had no choice really as cheese and chocolate have made me gag) and 'despite' this have still put on 2.5 stone; going from 9st 4lbs to 11st 12lbs. I don't put on weight easily (when not pregnant). Hopefully this info has reassured mums worried about weight but the curious in me wonders what the likes of Kate Middleton/Sienna Miller etc eat or do in pg that is do different to the rest of us.
