Some things you must eat, and others you must avoid or limit. Foods rich in irona are important, for in the womb the baby is storing up enough iron to last it for six months after its birth. You need more milk (cheese is also good) to supply the calcium your baby needs for building bones. And a balanced carbohydrate intakeb will help to avoid excessive weight increase. True, you may be eating for two of you, but one of you is very, very tiny!
