Does a stomach really grow this fast? More than halfway through my third pregnancy, I'm noticing something I didn't while expecting my daughter and son —belly expansion by the hour! The other day I woke up barely looking like I was with child, but by the time I went to bed — it seemed like I was nine months along. This continues to happen on a daily basis and other mamas have told me they experienced the same thing whether it is due to food, beverage, water retention or the impending babe's movements. Did you notice this daily stretch?
