my favorite is using nasal saline drops (with or without the suctioning). the saline helps to loosen up the mucus and promote drainage and the saline also helps to shrink down the nasal passageways -- allowing for more air passage. since it is just salt water you can use it as often as you like and it is pretty inexpensive. .
how can we treat our 6 month old who has nasal congestion that only seems to bother him at night?
