Hernia in 4yo?

[SoupDragon]

I'm taking DS2 off to the doctors tomorrow, something I've been meaning to do for ages. He has a soft bump about 2 inches above his belly button. Sometimes it's more noticable than others and I tend to think "must take him to the docs" and then forget about it because I don't see it (bad mother!)

Is it most likely to be a small hernia? There don't seem to be any other symptoms or anything.

Dd2 has one in exactly the same place. She was reffered to the hospital for it but they said it was ok and nothing to worry about.

They said if it bothers dd when she is older then they would do it then.

Thanks Hopefully DS2s will be the same then.
