Pick it up and pat it on the back.
When a newborn baby burps, it can be prevented by preventing the diaphragm from contracting. The specific way is to pick up the baby, then pat the baby on the back and give him some water to make the baby breathe more smoothly. If you can put your hand under the baby's foot and massage, the massage intensity does not need to be particularly large, so that the contraction phenomenon will stop more appropriately, thus avoiding the newborn from burping all the time.
Slight itching
If the baby just burps a little, you can use another method, that is, put your fingertips on the baby's bed or next to your ears and tickle them gently, which will make the baby's hiccups disappear, because tickling will relax the baby's nerves, but be careful not to scratch the baby's skin because the nails are too long when tickling.
