Babies do not usually need burped all the time unless they swallowed air and have gas buildup in their stomach.
But it's a good idea to still at least try to burp the baby before putting the baby to bed and sleeping.
The baby may wake up fussy or may not go to sleep and keep you up and be fussy or cry until you burp the baby.
I always burped the baby before putting the baby to bed for the night.
It doesn't take very long to burp the baby before putting them to bed and that way you don't need to worry about them waking up fussy and crying and then having to burp them.
Burping a baby is where you pick the baby up in your arms and then place them against your chest with their head facing the back of your body and then you pat the baby on the back.
As you pat the baby on the back gently it should cause the baby to burp out gas or air they had built up in their stomach while feeding.
Bottle fed babies usually get the most gas but even breastfed babies can also get air trapped in their stomach as well.
Burping the baby gets that gas or air out of their stomach so that they are not choking on it or become fussy.
After every feeding you should burp the baby or try to burp the baby to make sure the baby has no air trapped in their stomachs.
Otherwise they become fussy and cry and cry until you do relieve that gas in their stomachs by burping them.
Sometimes they may spit up on your shoulder while burping them so have a burp rag or washcloth on your shoulder before you burp the baby.
