do they work on newborn poos too?
They work beautifully - although not really sure about those first few poos (you know the black ones). Used my from very early on and it has made things nice and easy to remoove the "sticky" liquid type poo from the nappy before hitting the washing machine - although now that DS's poo is more solid I almost don't need it - he still has the odd sticky/liquidy poo that is best removed with the LS. (We have only had BM and normal solids here, no formula so don't know if that makes a difference)
