Its been said that everything is OK in moderation and when it comes to kids hygiene this is also true, particularly in the early stages of growth. Of course washing hands before eating and after toileting is an important life skill that your child will need to learn, whether at home, in kindergarten or at preschool. Daycare centers are also big on including this as part of their normal routine.
However when your child is still a baby its important to know that a little bit of dirt is actually good for them! As the body is only able to cope with the germs that it recognizes its important to let your little one become exposed naturally to what is in the surrounding environment. This way her immune system will be able to mount a coordinated response when greater exposure arises.
We have all seen the baby at the park putting dirt in their mouth with a screwed up look on her face- keep it in mind that this has been going on since the dawn of time.
