I took this photo to use for a talk on the negative effects of mouth breathing- It made me laugh so I wanted to share it.
Seriously, in a child that can nose breathe, micropore tape (not gaffa!!) is a great way to maintain their lip seal overnight forcing them to breathe through their nose. Only use for a child that is old enough to remove the tape in case of sudden gastro, or any other reason. Never use if they are unable to breathe through their nose for any reason
