See the pediatrician: The way you describe it, these findings could describe a condition called a patent urachus. During fetal development, a tube from the bladder to the belly button, called the allantois, conveyed waste to the mother through the umbilical cord. This tube usually disappears, but can stay open, with urine collecting in it, or even leaking out of the belly button. See your pediatrician first.
