Decreasing your baby's mucus production is possible by thinning out the mucus usually caused by colds and other viral infections. Mucus buildup and the resulting congestion your baby may experience can make it difficult for your baby to sleep or eat; in some cases, large amounts of mucus may cause choking. Since the American Academy of Pediatrics does not recommend the use of over-the-counter cold medications in babies and children, the best recourse is to use at-home remedies that keep your baby's congestion under control.
Offer your baby plenty of fluids through his regular feedings of formula or breast milk. There is no need to increase feedings, but encourage him to eat as he normally would when he is not sick.
Give babies older than 6 months old warm liquids, such as broth or chamomile tea, in a sippy cup.
Run a warm-mist humidifier in your baby's room while he sleeps to moisten his airways and break up mucus.
Place a rolled-up towel or a pillow under the head of your baby's crib mattress to elevate it. This places your baby's head up, allowing the mucus to drain instead of building up.
Run your shower on hot with the door closed and sit with your baby in a bathroom during the day whenever he seems congested to break up the mucus.
