A baby will take in air into his tummy during feeding. Therefore, it is necessary to help him let off the air through burping less he throws up. It is advisable to burp him when changing breast (if breast feeding) or after every 2 to 3 oz.
The first technique that I've learnt was to place Ryan on my lap. Using the left hand, place his head against your left hand, supporting his chin using your index finger and thumb. Use the base of your left hand to gently press against his tummy. Lean him forward slightly and gently pat or rub his back or shoulder using the right hand. (See second picture)
The second technique is to place his against your chest with his head slightly over your left shoulder, supporting him with your left hand. Using the right hand, gently pat or rub his back or shoulder. (See picture on the first picture). Make sure you have a napkin placed across your shoulder unless you want him to throw up all over you.
Burping the baby takes a lot of patience. He will sometimes burp after a few pats or immediately the moment you sit him up or lean him against your shoulder. Other times, it could take a good 5 to 10 minutes before he will burp. The other trick that I've learnt is to put him down and sit him up again a couple of times if he refused to burp.
Believe me, there is a great sense of unexplained satisfaction when he burps and it is pure music to my ears. And it is interesting to note that no two burps are exactly the same! Pay attention and you will find out.
