A baby stroller and a lateral seat cover portion thereof are provided. The lateral seat cover portion of a baby stroller includes a fabric bag including an inner side fabric and an outer side fabric opposite to each other, a foldable plate wrapped in the fabric bag and located between the inner side fabric and the outer side fabric, and an auxiliary device. The foldable plate includes a first plate and a second plate pivotally connected, when a frame of the baby stroller in an unfolded state, the foldable plate is in an unfolded state. When the frame of the baby stroller is folded, the auxiliary device enables an outer side of the first plate and an outer side of the second plate to approach each other, thereby switching the foldable plate from the unfolded state to a folded state.

an auxiliary device, wherein when the frame of the baby stroller is folded, the auxiliary device enables an outer side of the first plate and an outer side of the second plate to approach each other, thereby switching the foldable plate from the unfolded state to a folded state,
wherein when the foldable plate is in the unfolded state, the foldable plate is provided with a slot between the first plate and the second plate, an inner side of the first plate and an inner side of the second plate are spaced apart by the slot; and
when the foldable plate is switched from the unfolded state to the folded state, both sidewalls of the slot prevent the inner side of the first plate and the inner side of the second plate from approaching each other.

2. The lateral seat cover portion according to claim 1 , wherein the foldable plate is provided with a through hole.

3. The lateral seat cover portion according to claim 1 , wherein a width of the slot is less than a sum of a thickness of the first plate and a thickness of the second plate.

4. The lateral seat cover portion according to claim 1 , wherein the foldable plate is an integrally-formed element, the slot is located on an inner side of the foldable plate, and a depth of the slot is less than a thickness of the foldable plate, and the first plate and the second plate are pivotally connected via a bottom wall of the slot.

5. The lateral seat cover portion according to claim 1 , further comprising:
at least one pivot member, wherein both the outer side of the first plate and the outer side of the second plate are connected to the at least one pivot member.

6. The lateral seat cover portion according to claim 1 , further comprising:
