My daughter is getting more interested to some difficult questions. For example, last night she was reading a book about health (which is not kid's book) then she asked me what is cancer. I know what is cancer but how can I explain correctly about cancer to seven years old kid?
So I typed some words on Google and try to find a nice website that can give me good information to explain my daughter's question. Explaining something like that to small kid is not the same with explaining the topic to grown up person.
Luckily we have Internet. We can search many kind of information that can be useful for our life. So I found some very good sites which explain well about health topics in kid's way.
