Many mothers feel that it would be horrible to have another woman feed their babies, and they would prefer to give formula milk, if they are unable to breast feed themselves. Perhaps this is because mothers feel anxious that their baby may bond with someone else. In fact, you needn't worry. Breastfeeding by another woman, even someone who is not a member of our own family, has absolutely no harm in it at all. Many women feed their babies formula milk.
Some women do it because they feel they are too busy to breastfeed.
Others do it because they were not able to get the help they needed to breastfeed. Almost no mothers are physically unable to breastfeed. As long as you bottlefeed correctly with strict hygiene, use safe ingredients and provide extra nutrition like iron and vitamin D after six months, the baby will receive sufficient nutrition. But it's hard work to bottlefeed. Otherwise, you can make the baby ill or undernourished.
