Took my DS to the theatre today and saw a lady place the potty down for her 3/4 year old DD in the middle of the toilet, whilst she used the toilet herself...
Who does this?
I understand long days outside and special need's/phobias involved, but her daughter was asking to use the normal toilet.
I then saw her again on leaving the theatre placing the potty down by the exit for her daughter to use again???? 
If I am extremely ignorant please enlighten me as to the reasons? I'm genuinely interested!
