In short, yes. Tummy time, or "prone play" has been shown to help reflux however I know from experience how frustrating it is to have a baby that spews every time your put baby on their tummy. Adding an incline support - such as a pregnancy wedge, is a great way to reduce reflux symptoms in tummy time for younger babies (0-4 months) Fortunately, although it looks like a lot of milk, the volume is not as much as you think. Keep an eye on your baby's weight and make sure it isn't dropping - if it is check in with your GP.
