So I bought this chair for my tot (16 months old) and I went to sit her on it and her feet barely touch the floor. She looks very akward in it. I think its too tall for her. Its the saftey first 3 in one or something like that. I was considering the babybjorn potty chair but not sure if it would also be too big. What about the design of the chair? seems like it would be better with a removable cup where the pee/poop goes for easier cleaning. Help, not sure what to buy.
