Cleanse your breasts with H2O (or your own milk) before and after feeding.
Cramps are very common in the first weeks as your baby is trying to get used to feeding and his or her tummy and intestines are still learning what it is that they are supposed to be doing. Stay calm, try the different ways of soothing your baby and remember stay calm. Stick with one remedy if you must use one, rather than change all the time.
ENJOY your baby, he, she is really quite strong, very cute and changing very quickly. By just relaxing and following your instincts you are more than likely doing just what you should be.
Should you have any questions,you are most welcome to phone your midwife.
