An infant care device and mattress for use with the infant care device for supporting the weight of an infant during normal use and during resuscitation. The mattress includes a non-Newtonian fluid that supports the weight of the infant. The non-Newtonian fluid allows the mattress to act as a pressure diffusing mattress when the infant patient is placed on the mattress for an extended period of time. The non-Newtonian fluid reacts to a force applied to the mattress, such as during resuscitation, such that the non-Newtonian fluid stiffens and provides the required support for the infant during such resuscitation. The non-Newtonian fluid is contained in one or more flexible pouches positioned within a mattress body. The mattress of the present disclosure thus replaces the need for a separate foam mattress and pressure diffusing mattress.
