Cleaning: You should clean your breasts with warm water at least once daily then dry it out with a clean towel. Put lanolin creams or olive oil or coco butter cream on your areola and nipples at least 3 times per day to avoid nipple cracking. You should clean your hand well before breast feeding and also clean the nipples well before and after breast feeding. If breast cleaning is not done well, it might end in inflammation of the milk ducts.
Clothes: Avoid tight bras or bras with wire supports. Simple wide and cottons bras are preferred. No hard contact should be between your nipples and clothes and avoid using any irritating or allergic agents on your breasts.
Nipple Cracks and pain: it is caused by the baby not latching on the nipple the correct way or due to inflammation. If the cracks or pain is so severe avoid breast feeding with the affected breast for a period time till your breast heals and in the mean time draw the milk out by gentle massage of the breast and not by suction. If you feel good start breast feeding with the affected side again, but if your healing is slow consult a doctor.
Breast congestion: You can gently massage your breast during breast feeding and you can also use warm clothes over your affected side before feeding. Try to breast feed on close intervals to empty the breast. You can visit your doctor if the situation persists.
Breast milk amount: If you feel that your breast milk is not enough you have to check with your doctor. Milk release depends on repeated sucking of the nipples and breast .When the baby sucks the nipple 2 hormones are released prolactin and oxytocin. The former is responsible for making milk and the latter is responsible for ejecting the milk.
