That's right.  I learned, while doing this schoolwork that until s/he is six months old, a human baby doesn't need any other food, not even water, just breastmilk.  It has everything the baby needs: vitamins, proteins, minerals.everything in the right quantity- not more or less!  
 
That's cool!  But are you sure about that?  The baby won't die of starvation or thirst if  it only drinks breastmilk? 
 
Of course not! Scientists have done a lot of research to guarantee that.  But, after six months of age, babies need to start eating vegetables, fruits and other foods along with the mother's milk... 
 
Hmmm.Do you mean that my aunt who is going to have a baby next month, doesn't need any of those pretty bottles with all those drawings of animals that she bought for the baby?
