I want to start using cloth nappies on my 4 week old son (i was waiting until now to recover a bit from my c-section, as advised by the nappy lady at my hospital). I've got Bambino Mio's and a few Tot's Bots. What is the best barrier cream to get, to try and prevent nappy rash? If it makes any difference, my skin is quite sensitive to too many chemicals. Thanks.
