Breastfeed alone is the best food for babies till the first six months of birth and after six months mother's milk can be given along with other food products. World health organization has recommended mother's feed for at least two years of birth because mother's milk has all the nutrition needed for the growth of the baby and it prevents babies from many health problems in the initial years of birth. The baby who takes mother's feed has a higher immunity against infections as compared to baby that drinks formula milk.
How and when to stop lactation, depends mostly on mother's choice. You can decide to stop giving breastfeed after six months or after a year depending on your circumstances. Sometimes, the baby enjoys food given along with the breast milk and you can reduce the amount of breast feed from four times in a day to two times in a day and then to one time, before stopping it completely. It is going to be tough in the initial few weeks for you to stop giving breast milk as the milk leaks and it can be annoying to see the baby cry for it. You may have to express milk out and will have to be strict on not giving the feed to the baby, as you once decide. You can consult your doctor about it before planning to stop nursing.
Baby bites: When the baby has first teeth, she may try to bite everything she gets and she may even injure the nipples. You can end the feed, if the baby bites because biting can cause injury to the nipples, which may get infections and it can cause sores. If the baby is more than twelve to eighteen months old, you can end lactation if the baby bites and try to provide the baby nutrition form external sources and if the baby is small, you can express the milk and give it to the baby when she needs it.
Another pregnancy: If you are pregnant again, the need for nutrition increases and you may need excess nutrition for the growing fetus. You can stop nursing although there is no other harm of nursing on getting pregnant.
Baby's need for food increases: If the baby needs more nutrition as she grows, your breastfeed may not satisfy the baby. You will have to increase the quantity of external food products and reduce breastfeeding.
Infection in breasts: You can immediately stop nursing if your busts get infected. You can consult a doctor in case of any medical problem related to busts.
Lack of spouse's approval or feeling uncomfortable while nursing in public: Many women find it difficult to give the feed in public and to prevent embarrassment; you can limit the lactation to early morning and night. Give only formula milk or other food products during the day, when you are out with the baby. But it best advised to feed the baby for at least six months.
