My son will be 2 weeks old in 2 days and has been very fussy and uncomfortable the past 3 nights producing bm. he's been eating as usual and urinating?

So young: Your child may be fine yet I wonder does he have a fever? Also is he vomiting? Is his belly real bloated? I would prefer if you see the doctor and have his vital signs verified and perform a physical exam. If nothing else, it will reassure you that you are doing everything right. He may just have "gas" but I would prefer that he is seen by a doctor. Thank you and good luck.
