Since 5 pm (now 3:30am) baby has been fussy non stop and crying. I checked temperature he doesn’t have any. He does have some acid reflux problems which the dr changed his formula for. I don’t know what else to do 😫 should I wait until morning to call dr or does he need to be seen sooner? Has this happened to anyone? I’m a first time mom so I’m freaking out
