Write NO MORE THAN THREE WORDS for each answer.

Babies, especially newborns, have the smoothest and most sensitive skin, and react to almost everything that touches them. This is why we have to be sure that whatever they come into contact with doesn’t have any bad effect on their skin.

Organic (有机的) newborn clothes are gaining popularity these days for being made from organic, non-synthetic (合成的) materials produced without pesticides (农药) or fertilizers(化肥).

Organic clothes are produced from organically-grown cotton on fields. We want only what is best for our babies, and organic clothes for newborns can help protect them from being exposed to the poisonous substances sometimes present in the clothes we normally wear. We don’t want our babies to get rashes (皮疹) just because we weren’t wise enough when buying their clothes!

What else do they offer? They wash more easily than ordinary clothes, giving better value for money in the long run. Ordinary clothes cost less, but the material they are made from is subject to frequent wear and tear even before it is made into clothes. In the long run, then, organic clothes are not only better for your child, but also more cost-effective, and remain fresh and in good repair after many years of use.

You may think that organic clothes must be dull and lifeless; nothing could be further from the truth. Modern techniques enable these clothes to be designed in attractive and brilliant colors with adorable patterns. Your clothes are not only safe, but beautiful as well!

In short, organic clothes are definitely an option to keep in mind when you’re shopping for that soon-to-arrive member of your family.
