A multi-purpose child support device comprises a frame having a base for placement on a floor surface and a support section positioned above said base. A seat element is configured for receiving a toddler child in a sitting position and is coupled with the support section above the floor surface for forming a high chair. The seat element is displaceably mounted to the frame and is operable for being selectively removed from the support section such that the support section receives an infant child carrier for supporting an infant child carrier above a floor surface.
