Putting plants in young children's rooms can be a divisive subject if you want to bring in health and safety hence why I have resisted writing this blog post for a while. So to be clear – I am talking about babies and very young children and I am assuming that they are supervised (or left in their cot) in their nurseries/ bedrooms and unable to gain access to the plants to be able to do themselves any harm! So – why plants in babies rooms? 1. Plants are natural air filters.
