My son, 7 weeks, has a umbilical hernia. does this mean when he was born he wasen't fully developed & how concerned should i be? (stressing already)

Normal at birth.: The blood vessels that connect the baby by the cord to the placenta enter/exit through a small opening in the abdominal wall, and after birth, when the blood vessels contract and the cord falls off, the underlying perineum (firm tissue lining the abdominal cavity) contracts to tighten the hole. Some times this takes months or years. Until that happens, the skin overlying may bulge = hernia.

Umbilical hernias: are defects in the abdominal wall that many babies are born with. They protrude more during crying or vomiting, but should always be soft and flesh colored. You should easily be able to push it back in. Many of these correct by themselves by about 2 years of age. A simple surgical procedure can be performed in those that do not. Only very large hernias increase risk of bowel entrapment.

Kids seldom need rpr: Loose belly muscles help a developing baby by allowing easy blood flow thru the umbilical cord & into babies body. After birth, that loosness may allow a transient umbilical hernia that will usually disappear when the belly muscles tighten, starting after baby learns to sit.By 2yo most uh have receded. I find girls more likely to need repair than boys.I rarely refer for repair <2y.
