According to She Knows, hunger is a very common first symptom of being pregnant. Oddly enough, hunger and nausea go hand in hand. As a result, sometimes the expectant mother is nauseous with regard to certain foods, and she craves others.
She Knows says that while it's fine for expectant mothers to give in to some of their cravings, it's important for them not to go overboard. Finding a balanced diet is extremely important not only for the mother but for the baby as well. Using the excuse that she is eating for two is not a healthy outlook on pregnancy and does not give the expectant mother free rein to eat her own weight in potato chips and ice cream.
