What can I do to soothe my baby's tummy?
Its normal for babies of this age to get full and gassy, but rest assured that as her intestinal tract matures, shell have a much easier time. That said, I have had great results decreasing a breastfed baby's gastric distress by changing the moms diet. Eliminating dairy products, eggs and peanuts can make a huge difference; these protein-rich foods can make breast milk harder to digest. If you do eliminate dairy and are worried about getting enough calcium, take a calcium-magnesium supplement.
In the meantime, try burping your baby more frequently. In addition, switch breasts only once during a breastfeeding session. This will decrease your milk flow slightly, ease her digestion and decrease her gas.
