I'm not sure this is the best place for this question, but I can't immediately find anywhere more appropriate.
This is my first baby and we're trying to sort out what we'll need, however we're very pushed for space (and quite pushed for money). The "standard" nursery seems to include a changing table or similar piece of furniture but I had planned just to use a changing mat on the floor. Is there any real reason why I shouldn't just do this? I have heard people say it's bad for your back, but I can't really see how lifting a child from the floor can be any worse than lifting them to waist height or above to put them on a table.
What are other people's experiences?
