Lung Exercise

Colt has been testing out his lungs to make sure they work via constant crying. He cried for like 6 hours last night, and another 5 today. And I tried everything...literally, everything so I don't know what is going on. He has never been fussy ever- at the hospital at least. Tomorrow we have a ped appt in the morning, so hopefully she can give us some tips. I was really worried he might be getting sick or something, but no fever or other signs of anything that I can see. A bath seemed to calm him down and he went off to slumber land finally!
