Anyone have any advice for a baby who is constantly spitting up? I’ve tried feeding him smaller feedings and burping him more often and I keep him sitting upright for quite a long time after he feeds. He doesn’t seem to be in pain at all and his spit up is white, not yellow or green. I am constantly changing his clothes and doing laundry which is not a big deal, mostly I want to make him as comfortable as possible. Any other advice that has worked for your littles? Thanks in advance!
