I used to get mildly excited when I tried a new shop's own brand, but found they were all pretty much the same. Pampers and Huggies were total waste of money as they were no better or worse than Tesco and Asda own. Found the value brands were crap but they did when I couldn't afford anything else.
Reusable nappies are far more exciting. Trying a new nappy was almost like getting new clothes. Am quite sad now that ds2 is out of nappies as I've not got an excuse to trawl websites for new wraps, stuffables or bargain tots bots (sniff). Will have to persuade dp to help me produce yet more offspring!!!
