I'm worried that my 3-week-old son has some sort of gastrointestinal problem.
For the last five days or so he's basically been crying nonstop whenever he's awake. Hours at a time. It seems mostly like infant dyschezia because he's often grunting and straining. He does poos but just a few minutes afterwards he is in discomfort again.
Now, his poos have just turned green. Previously, they were yellow / pale brown.
He's pretty much exclusively breastfed.
I had two courses of antibiotics while pregnant, two more since he's been born, and he had to have a course at birth too. I'm worried all those antibiotics may have messed with his microbiome.
He just seems to be in so much discomfort all the time, and now that his poos are green it seems even more likely that something is wrong. I really hate it and don't know what to do.
