Ladies I don't have any liquid to put in this? How else could I use it my son has a bad cough and can't sleep?

If it won't steam with just water add a pinch of salt to the water and give it 10 min works everytime

you are quite welcome

@sarahdrew, thank you so much

just the water inside it will help... if you have vicks rub put it on baby's feet

@sarahdrew, I just put water instead on top?

just water mama it will help

Yeah I'm doing it right now. But I wanted to do it over night too

It wouldn't be using that but you could do a shower steam treatment !
