A portable changing table is disclosed. The portable changing table comprises a flexible support material and a support pocket disposed within the flexible support material. A rigid planar material is disposed within the support pocket and rigidly supports the flexible support material. An extension extends from the flexible support material and forms a securing envelope configured to attach to a child safety seat or a child stroller. Securing straps attach to the flexible support material and are configured to attach the flexible support material to a child safety seat or a child stroller. The securing straps and securing envelope provide tension across the flexible support material to provide a rigidly supported substantially horizontal surface where a caregiver can change a diaper or clothes of the infant or small child.
