oh, see I did use the baby bath a lot, because it's a lot quicker to put the baby bath in the main bath and just fill that, rather than fill the whole of the big bath (and saves water). I'd actually often wash DCs in the baby bath in the shower cubical, quick to fill, easy to hold them (no leaning over the big bath) and just tip into the shower tray to empty...
I also would say a changing table is worth having, particularly like me you end up damaging your back in labour, having to kneel and lean over to change nappies on the floor would have been a nightmare for the first 2 months when I really needed to stay upright as much as possible.
Wastes of money:
Top and tail bowl, waste of money, any old bowl would do.
changing mat liners, just use normal handtowels.
overly complex breast feeding clothes - always hideous shapes. Go with t-shirt with vest (with stretch straps, ideally a size up) underneeth. T-shirt goes up, vest pulled down, minimum exposure and you can wear real clothes!
Agree not with a special bin, just any old bin and lots of liners - special bins just seem to encourage people to store shit in their houses.
