Hi, are there any travel cots/portacots that Red Nose recommends please? A quick Google search has shown that a lot don't meet safety standards. Thank you

Red Nose recommends using a porta-cot that meets the Mandatory Australian Standards.
It is important to read the instructions that come with your cot, specifically related to mattress & weight of child.
Only use the firm, thin, well-fitting mattress that is supplied with the portable cot. Never add a second mattress or additional padding under or over the mattress, which has been specifically designed for the portacot, as baby may become trapped face down in gaps between the mattress and the sides.
Do not use a portable cot if your child weighs more than 15kg (or check instructions of your particular model)
