After you have prepared the formula, shake the bottle well, and do a temperature test. Allow a drop to trickle on the back of your palm or the inside of your wrist and see how warm it is. Any formula that’s left in the bottle after a feeding must be discarded. Unused prepared formula should be refrigerated right away. Do not use prepared formula that has been lying in the bottle, unrefrigerated for over an hour.
Once the baby has finished feeding, you must burp the baby. At all times keep a burp cloth ready. Gently put the baby on his stomach over a burp cloth and slide your hands over his back a few times till you hear a burp. Or hold him such that his head is over your shoulder, and pat his back gently. You might want to drape the burp cloth over your shoulder when you burp him this way. Babies might not always emit an audible burp. But rubbing your hands over his back and patting him will eliminate the buildup of air bubbles from his body.
