Nasal congestion is a common problem for children resulting in thick nasal secretions.
Weather changes, colds, or allergies can cause nasal congestion. Babies will often have problems with congestion because they are nasal breathers and do not breathe out of their mouths except when crying. Helping to clear the nasal secretions of newborns and infants can be done with saline nasal spray and a bulb suction. The saline nasal spray is easy to use. First, turn the saline nasal spray bottle upside down and place two drops of saline into each of your child's nostrils.
