It is difficult dealing with a nurse who is set in her ways! SIDS & Kids will only ever recommend a cot with firm fitting mattress, they do not endorse any other products. The Amby Baby Hammock promotes safe sleeping as it keeps babies positioned on their back. The constant natural motion is said to prevent the build up of carbon dioxide around baby (a possible cause of SIDS). The new design Amby Air was designed based on advice from a representative from Standards Australia. It meets all the relevant parts of the British and European safety standard for cradles and cribs, so it is definitely a safe product! It is used in hospitals, mother and baby units and day care centres all around the world and is recommended by many paediatricians, midwives, neurologists, chiropractors, etc. due to their many health benefits.

I hope that helps!
