Two different editions of HP series one for kids and another for adults?

I recently found out about this and I'm confused. I have to mention
that  I am not from the US nor from Britain so over here (in Romania
that is) we only got the Blomsbury editions in English and the one
translated in Romanian (which is dreadful by the way). So the
Blomsbury edition is for adults or for children? What is the
difference between the two editions? I heard that some lines were left
out in the children editions. Is that true? Does anyone have the
missing lines from the children editions from the 6 books? Are those
lines important to the books? Do they refer to Severus?
