Humidifier for a nightime chesty cough?

[milkyman]

Do these work for a preschooler, if so which one is best for a fairly small room?

Just watching this as am also on the look out for a cold mist humI different but it's a bit of a minefield !

Worked instantly for my toddler.

I bought a cheap one for £20 from Argos.

Mine works brilliantly for my son. We've had it since he was about 18months & it really helps if he gets a nasty cough
