These are less harsh than other baby wipes and consequently, really good for the smallest of babies- I would say okay to use from four weeks old. There is a slight earthy smell, so I wouldn't say completely odourless, but nevertheless, not an offensive one. On the plus side, they are also great for taking off my makeup. However, they are not cheap and so in these times, the average mother might be tempted to opt for the cheaper version. It is good to know that they are less harmful to the environment however. All in all, a great product for babies.
