ABSTRACT:
A childcare instrument or baby carriage has a core member contained removably in a bag placed on the rear side of the carriage, and the core member includes a first plate member and a second plate member arranged to overlap each other. The first plate member has first apertures piercing therethrough in the direction of thickness. The second plate member has second apertures piercing therethrough in the direction of thickness, and the second plate member is relatively displaceable between a first position to align the first apertures with the second apertures and a second position to displace the first apertures from the second apertures. The childcare instrument thus provided is accordingly capable of adjusting the degree of breathing.
