Possible hernia?

Lauren

This is what my sons belly looked like while he was sleeping. He’s 2 weeks and 3 days old. He pooped and it went away. The doctor diagnosed him over the phone with a hernia and said to just make an appt next week because it isn’t an emergency. (The other pedi is who I talked to in my sons pedi office because his is out) Have any of you ever seen this? I freaked out. Please let me know what you think.
