Hi all, we use a mixture of Itti Bitti SIOs and Lollipop microfleece sized with tots bots or nature babies wraps. While DD does not smell at all in the Ittis, we can now not even use the Lollipops/wraps, as after the first wee she smells really strongly of UTI! I really need to get them back into circulation. I normally wash with a teeny bit of persil non-bio, a bit of mio sansitiser and some white vinegar. I never wash particulalry hot as worried about the wraps/Itti outers - could that be it. Can't imagine it's a soap build up as hardly use any. Any tips?
