I would spend half on the one's your swooning over ( what your heart tells you) very baby nappy and the other half on the birth to potty ( what your head tells you). Was just thinking if you bought all very baby nappies and then couldn't sell them all you would be a bit stuck!
Also thought that if you buy only sensible nappies that you aren't in love with you will get fed up of them and end up spending more money on new cute nappies you can't resist! So half and half best of both worlds!!
