Why does a 1-month-old baby spit up with mucus?

Mucus-containing (slimy, sticky) spitting up in a 1-month-old can result from several causes:
The most common cause is unswallowed nasal drainage or postnasal drip going to the stomach and coming back up as spit-up. In this case, you may see clear or whitish mucus particles in the spit-up.
Another possibility is reflux. In 1-month-olds, since the stomach-gut muscles are not yet mature, mild reflux is common and sometimes stomach fluid may come up with the milk.
Conditions that warrant concern:
- Spit-up contains yellow-green bile or blood
- Baby spits up forcefully after every feeding
- Baby has difficulty breathing or persistent cough
- Baby has a fever of 38°C or higher
Under these circumstances, I recommend seeing your pediatrician. If spitting up is infrequent and your baby seems well overall (nursing well, alert, adequate urine output), monitoring at home is usually sufficient. Holding baby upright after feeding and burping can help.
