Occasionally, babies take in too much milk at once and gulp in air along with it, causing gas. If your baby is popping off the breast, gasping for air, or making clicking sounds while nursing, those are signs that you may need to alter your technique. Hold your baby in a more upright position so the milk can travel down her throat more easily. If your letdown is too strong or your breasts are too engorged, try pumping for a while before you breastfeed. If the problem persists, you may want to see a lactation consultant. --Laura Flynn McCarthy
