I am reading so much conflicting information. Some say that the Lullaby Trust have stated that items such as the Sleepyhead increase the chance of SIDS, yet many say it is a life changing item they cannot live without. I am contemplating using it for daytime naps as we will have a bedside crib for night, but can’t understand if it is safe to use on a sofa or should it be on the floor? The guidance is very vague, and I just wondered how other people use theirs? And are you not concerned with the supposed risks?
