Ideally, all items included in donated bags are new, sealed in their original packaging. Nappies (and other items) can be put in a reusable shopping bag or tote bag to be attached to the Mum & Bub bag in case all the items do not fit in the bag. However, loose nappies must be placed in a zip lock bag or something similar to protect them from contamination/damage/leaked products. We want to make sure we keep our vulnerable little ones safe from harm where possible.
