<p>A sleep inducing device for inducing sleep or settling of an infant when in a pram in the form of a floor mat provided with an uneven upper structure having at least two spaced apart upwardly extending projections in the form of rectalinear ridges extending from one side of the mat to opposite sides of the mat. The height of each ridge and the spacing apart of adjacent ridges is selected to replicate the 'lub dub' sound of the heartbeat of the mother of the infant when the pram is pushed over the surface of the mat by the wheels being deflected upwardly and downwardly to produce vibrations as they pass over the ridges. The surface of the mat is also provided with undulations between adjacent ridges. The mat provides an economical and easy way to settle an infant where required by placing the mat on a suitable floor surface and repeatedly pushing the pram backwards and forwards over the mat until the infant settles and falls asleep.</p>
