6. The foldable children's toilet ladder according to claim 5, characterized in that: The auxiliary support rod (12) is provided with at least two groups of first hinge holes for mounting the pedal assembly (3), the main support rod (11) is provided with third mounting holes corresponding to the first hinge holes, and the pedal assembly (3) is provided with support grooves (32) corresponding to the first hinge holes. The pedal assembly (3) and the supporting crossbar (5) are respectively adapted to the first hinge holes and the corresponding third mounting holes, so that the pedal assembly (3) can be horizontally unfolded.

7. The foldable children's toilet ladder according to claim 3, characterized in that: The main support rod (11) and the auxiliary support rod (12) are detachably connected via a connecting device (13), wherein the connecting device (13) comprises a first connecting member (131) and a second connecting member (132) which are threadedly connected. A second positioning groove (114) adapted to the first connecting member (131) is provided on the main support rod (11), and the first connecting member (131) cooperates with the second positioning groove (114) to enable the first connecting member (131) and the main support rod (11) to rotate synchronously.
