I am still looking for the potty. At the beginning, I want to buy a tradition one (痰罐). But, yesterday I saw the one like chair and 馬仔型 in Jusco. I would prefer the chair-like one as she can use for Poo Poo and as a chair as well. I think the 痰罐 without cover is not hygiene ;and the 馬仔型, BB will play rather than try Poo Poo. In Hang Fa Chuen, I saw the potty like a chair and the under can be a foot stand that for BB. I am still think about it.
