11 month old - lump under skin

[MiamiMint]

Hi, Have noticed in past few weeks that DS has a small lump under his skin above where his stomach is, but below rib cage. It is not there every day, but some days you can see it and feel it. Its like a bean just under his skin. Like I said, its not there everyday, and he is not affected by it, as in he is in great form etc.
Anyone else's babies have this or anyone had experience of it? I was going to bring him to GP last week but the day I was making appointment there was not a sight of it!

TIA!

Oh my DD2 had this and I took her to the doctor who felt it and said it was just gristle...it's quite a common thing apparently..I bet it's the same thing! Just take him when you can..the doc will find it and then your mind will be at rest.
