Abstract: A weather shield for an infant's seat such as a baby carrier, of a well known type having a carrying handle, formed as a shell into which an infant is seated. The weather shield is easy to use and comfortable for the baby including in main part an elongated panel to which triangular side panels are attached. A front section of the elongated panel is transparent permitting the baby to see and be seen. The elongated panel is made of a sheet material capable of shedding water, as are the side panels when the weather is intended for winter use. Snaps or the like are provided for attaching the weather shield to the infant's seat such that it cannot be readily displaced by the wind or by the infant.
