Hi there I understand your concern....add protein rich foods and healthy fats to diet for e.g..egg white...add fibre rich foods like green leafy veggies,carrots,Apple, etc. Add green tea to your diet .you have to eat more foods high in amino acids,calcium, zinc, iron, copper and magnesium...do regular exercise without failure......consult dietitian for further details naturally breast size increases during pregnancy and lactation...you can waite till that if no improvements even after that you can consult nearest plastic surgeon... The only way to increase breast size is by augmentation with breast implants which are placed behind the breast through an operation. You need to be comfortable with your breast size and whether you want to undergo an operation to insert the implants.
