In case you have an infant baby at home, you are probably losing good night’s sleep to feed them, change their diapers and stroke them to sleep while they are crying. This is natural and when they will grow up, you can set back in your routine sleeping schedules. But while they cry, do you often notice a small lump near their belly button? If yes, then you need to pay more attention to the same, as it is likely to be a case of umbilical hernia.
