Priscilla,
I grew up in Paraguay (South Asian parents), lived in the US for 22 years, and now I live in South Korea (where I teach history at an American-International school). I'm a classic TCK. my parents still live in Paraguay and I am currently buying an apartment there. We spend all our summers there.
Paraguay is, in my very humble opinion, a phenomenal place to raise kids. When my contract in S Korea ends, I fully plan on moving my two daughters there. While we only come during the summers, my girls have a TON of friends in Paraguay. The society is open and friendly, and foreigners are appreciated. There are some exceptions, and I can PM you about some better choices in terms of schools. Compared to Brazil and even Argentina, Paraguay is safe.
Downsides? No good museums (if that is your thing; as a history teacher it really is mine!). Arts are present, but not as strong as in other places.
All in all, it is a great place to raise kids.
