my wastes of money were -
baby bath (hurt my back bending over)
buying baby slings and carriers (kids hated them, Anneliese will only settle in the HAB)
rocking chair in nursery.

but i loved
my angelcare monitor - Anneliese had apnoea, so it was a lifesaver (literally)
change table - got mine from the 2nd hand markets for $5 and love it - had itfor 3 children now!
portacot - mostly used so i can give anneliese tummy time without the boys annoying her all the time
cot blankets - although we didnt use them when the kids were smaller, as they get bigger they come in handy (Anneliese is 7.5 months and the weather has cooled down alot lately so i've put one on her bed.
