One of the best things that we did for our kids here in Rio de Janeiro was to put them in a day care. We searched for the best and we finally found a place called Ativa-Idade, which means Active Age. Another huge benefit is that it is only about 1/2 a mile from our apartment so it is a quick and simple exercise to drop them off and pick them up.
Since going to the school, they get along better with each other and they talk a lot more. Although it is preschool, we get detailed reports on the kids progress. Or the best they can estimate given their age.
They have also made a deal with a professional photography firm that takes tons of photos of the kids events and they make them available on the web site for the parents and the kids. Here are bunch of photos from that web site. There are three events. Mother Day, a day in the park, and then something called Festa Julina. It happens every July and they try and dress the kids to look like little adults. Not sure why but that explains a lot of the photos. Check them out.
