The present invention relates to a smart diaper changing pad for weighing an infant or toddler and communicating the recorded information wirelessly to a mobile computer. The diaper changing pad incorporates force or mass sensors for measuring weight. The changing and cleaning pad and a separate computing system are wirelessly connected, either directly or through a network capable of both internal and external communication. An application installed on the mobile computer can track measurements from the diaper changing pad and keep a historical record, which may provide peace of mind and insight into a baby's health and development. The key components of the product are a soft pad, a rigid platform, one or more sensors capable of measuring force or weight, a power source, a memory, a processor, and a wireless communication method. The invention can optionally include a display and a number of user inputs such as buttons or switches.
