This nappy cream is the best product I have tried - and I tried so many products. My son has sensitive skin, and had an adverse reaction to disposable nappies. I tried all other nappy creams, including sudocream, benpathen, as well as vaseline. The rash got worse, and worse. I used Weleda Nappy Change cream, and the improvement was instantaneous. After 3 days, the rash that covered the whole nappy area has almost disappeared. We now use all of the other weleda baby calendula products.
Although it seems expensive, you only need to use a smidge and make sure that it's really well rubbed in.
