i use disposable but have used reusable ones before, we have a reusable nappy cleaning service here where they take your dirty ones and give you clean ones, so they were white, thats what the council told me to use when i had my 4th because there was only 10 months between them and our bins only get emptied once a fortnight so when i asked for an extra bin that was there answer. I did some research in this with a sales job i had and it didnlt work out better for the enviroment washing machine, washing powder, electricity etc, but i think its nicer on babies skin if you can use them. I really dont have the time to wash them and the service is not that cheap thats why i ended up on disposable, I dont know how my mum managed she had 5 and used reusable ones
