Post breast feed care of babies is a very important thing.
After feeding the baby either from breast or from bottle or from any other device baby should be burped properly.
Your health care provider will teach you proper burping techniques.
Commonly burping is done by keeping the baby upright on the shoulder of the mother and gentle tapping of the back of the baby 👶.
Sometimes the job might be tiring for the mother, causing pain or distress of the lower back. In such scenario, the mother may first choose a sitting accommodation which provides good back support like a firm straight-back type chair or using the wall as back support if sitting on bed (one can keep a pillow between ones back and wall ).
If the mother is exhausted other members of the family can take the role, like the husband.
