What is the difference between a 'pram', a 'pushchair', and a 'buggy'?
According to Google:
- pram: a four-wheeled carriage for a baby, pushed by a person on foot
- pushchair: a folding chair on wheels, in which a baby or young child can be pushed along
- buggy: a light pushchair with a soft seat that allows the chair to be collapsed inwards
It appears from the above definitions that a pram has four wheels (so those with three wheels should not be called prams?), while a buggy is a light pushchair (how light?).
I tend to think that a pushchair is the light one with four small wheels, while a pram is the heavier one with bigger wheels. But if a buggy is a 'light pushchair', how could it be that I have heard people calling what I think is a pram, a buggy.
Or can all these terms actually be used interchangeably?
