My baby was born early and keeps spitting up milk. Is reflux more common in premature babies, and does it improve over time?

Yes, reflux is more common in premature babies. The main reason is that the lower esophageal sphincter—the muscle that acts as a valve between the stomach and food pipe—hasn't fully developed its nerve-muscle coordination yet. In premature babies, this structure is looser, so milk can flow back up into the food pipe after reaching the stomach.
Over time—usually when your baby reaches 6-8 months adjusted age (calculated from expected delivery date, not actual birth date)—this muscle structure matures and reflux noticeably decreases. By 12 months adjusted age, it's completely gone in most babies.
Although the current spitting up may seem bothersome, for most premature babies this is a physiological condition that resolves on its own. If your baby is gaining weight well and shows no gagging or breathing difficulties, no additional treatment is usually needed. That said, I'd recommend sharing this with your pediatrician, since in some premature babies reflux can develop into gastroesophageal reflux disease—in which case a pediatric gastroenterology evaluation might be necessary.
