I think i lived on fresh air, yoghurt and dare espresso milk for a great part of my pg with Alister LOL. I just had no appetite either and only really ate when I got really hungry. And it certainly didn't affect his size either LMAO.

Just do the best you can with food and when you do eat make sure that it is wholesome and nutritious food as oppossed to junk. Don't forget too that babies are one of the most highly developed parasites known to man LOL - bubs will be taking everything it needs from you whether you eat or not, but you will start to suffer from it before the baby will.
