Hello, do you have any recommendation's for parents using bed rails when co sleeping ?

How old is your baby?
There may specific risk to baby who is less than 3 mths of age, premature or small for age.

Have you seen Red Nose brochure on Safer Co-sleeping (reducing the risk)?
https://rednose.org.au/downloads/RN0493_23_Co-Sleeping.pdf

We do not have any information on using bed rails when co-sleeping.
Bed rails can create a risk of entrapment if there are gaps (they are ill-fitting) or they are padded.eg bumpers/pillow.
