Hi - I’m looking to purchase a cot mattress. Do you currently endorse or recommend any particular mattresses or mattress brands? I’m also lookin for a step-by-step guide to swaddling with pictures. Thanks, Jacinda

Red Nose recommendations for a cot mattress is that it is firm, clean, well-fitting & flat.
There is a voluntary standard for mattress firmness which mattresses mostly comply to.

Red Nose does not recommend or endorse any specific brand name mattress.

How old is your baby?
There are many different ways of swaddling - here is Red Nose brochure on swaddling.

Once baby is rolling (or attempting to) swaddling should be ceased.
