Baby socks, I use MCN rather than terry flats. You use a tiny bit of detergent only in the wash. With two in nappies they are heaps cheaper. I bought nearly $800 worth of MCN to get started (and have only spent $20 since), and I had made my money back in 3 months (compared to sposies). They are better for the environment (like Ryn said), and also the sposies in landfill take some huge number of years to break down. Most MCN are natural fabrics which are better for nappy rash than sposies. I agree with the earlier TT too, if I put DS1 in sposies he won't use the toilet at all - in MCN he will use the toilet way more often. Also they look much nicer on their butts! I am sure I have left heaps of reasons out, but I was a late converter and really wish I'd switched to cloth earlier.
