Hi,
I am Dr Moorthy, Pediatric Surgeon. It seems your baby is having Inguinal Hernia (Protrusion of bowel through inguinal canal), which is a surgical problem and needs to be seen by a Pediatric Surgeon to confirm the diagnosis.
Next Steps
Ultrasound may help in confirming the diagnosis (Not always)
Health Tips
If it is a inguinal hernia, it needs to be operated as early as possible due to risk of bowel getting caught is high and surgery would be very straight forward, simple with 100% success.
