2 month old non stop crying. NEED HELP.

Alana • 22. Married. Mommy to Amanda Faye Hadley 5/1/18. Mommy to 3 fur babies 🐱🐱🐶

Took her in to urgent care (as the pediatrician in until Thursday doesn’t know anything....had probs w that ped to say that) did a normal exam and found nothing wrong. I think it’s a stomach bug (as she was non stop puking earlier but that stopped). Any advice on what to do because we are lost on how to help her so she’s not screaming her head off?
