Does anyone use these and where did they get them from? A lady at a mother and baby group asked me if i sell them and i dont but would like to advise. Also i am quite interested in trying them myself as i have a pack of nappi nippas hanging about and feel in the interests of my nappy addiction and store i should at least give them a try - how adventurous am i gettign for a pocket nappy devotee!!! I note terry squares etc.. come in different sizes - for a 19lb ds what size would you recomend? I know they will need a wrap which i have plenty of but are they bulbous in size when on?
