Would you place a child's bed next to an air vent in a chimney breast?

Changing rooms around in my 30s house and the only place to put my child's bed would be next to the chimney breast which has an air vent in it. The headboard would go up against it. Has anyone else got a similar set up as I've started worrying they'll be breathing in old fireplace dust as they sleep (downstairs is also blocked up now with a vent so wouldn't be used).

Am I being precious?

It wouldn’t worry me.
