Perhaps you are strapped for cash or maybe you just enjoy repairing and making things. If your bum genius need repairing there's help on that. I've come across people making their own nappies from old 100% cotton T-shirts. There are also people who hand knit nappy soakers. Do you know you can make soakers from old sweaters? There are even patterns for making a Maya baby sling.
Please let us know what you've found, made, repaired.
