Check Engine Light

Wouldn't it be fantastic if babies came with a check engine light?  I mean, I guess crying is kind of a check engine light for babies, but a simple little light might be better.  At least when a check engine light goes off you can take it somewhere to diagnose the problem.  Unfortunately, when Karter's check engine light goes off, his crying goes from a simple fuss to pterodactyl like screaming in a matter of seconds, leaving me little to no time to diagnose what his issue may be. I just wish he could tell me what is wrong or what would make him happy.  I feel like I should know just the right thing to make him happy because I am his mom, but I'm still trying to figure things out too.  I suppose until his cries are a little more definable all I can do is love on him as much as possible until he is happy again!
