This is a bulge caused by the umbilical cord as it enters the baby's abdomen. After birth, as the umbilical cord heals and falls off, the opening to the abdomen usually closes spontaneously. Occasionally the opening doesn't close, and you may notice a bulging belly button, especially when there is increased abdominal pressure such as during bowel movements or crying. Although it may look impressive, the hernia usually causes no problems, as long as the baby is comfortable and the area is not tender or extremely swollen. As long as the bulge is soft and compressible, and is not causing your child any discomfort, it's not a problem...consult nearest pediatrician they will do the needful
