I am due dc4 in 2 weeks and am tempted to try real nappies. partly for financial reasons and partly for the environment.How much would it cost for me to buy the initial nappies, liners etc. ? where do i buy from? what kind should i get? i have seen a terrys set at tescos which was cheap, will that do? will i just be giving myself loads of work? I really know nothing as have always used disposables.
