DS2's chest - see for explanation

[mysonshine]

I don't know the correct words so please bear with me. I was standing behind Ds2 (3yo) today and put my hand on his chest. His chest seems to be further out in the middle (between his ribs) then kind of slides down to the outside.
I thought this seemed weird so I called DS1 (6yo) over. His is like mine - the center of our chests are slightly "sunken". Does that make sense?

DS2 has had a croupy type cough for the last few days. But is much much better.

Is he ok? I've never noticed it before so I don't know that it's "new" or my awareness is heightened because he's been sick and I'm feeling it different.

I hope someone understands what I'm trying to say. I haven't been getting much sleep and can't think straight.

This is the only condition that I could think of Pectus Carinatum that might match your description.

I had a boy friend in my early/mid teen years with a 'pigeon chest' (a very successful competative swimmer) and it didn't cause him any problems (physically or socially, he was quite a hit with the ladies), it was just unusual from a anatomical POV.

I've no idea if this is what you've noticed with your son. Just thought I'd throw it out there as a possibility.
