reflux?

K • Baby #2 Due Aug 2019
Any other mom's with little ones seeming to be suffering from reflux? My son is 16 days old (born at 37 weeks, supposed to be a June baby) and has started spitting up more and more, last night we just couldn't get him settled at all and had to be upright. Seemed gassy and in pain and it just about broke my heart. I was crying and had to give him to my husband for awhile so I could get an hour of sleep in. Any advise? Going to call his pediatrician in the morning.
