"May this be a special and joyful day for you (...) Let there always be a smile on your faces, let every morning be the beginning of a new adventure for you," the presidential couple said in a video published on the president's website.
President Duda and his wife reminded children not to be discouraged by small failures and to always be positive. "It is up to you who you will be in your adult life," he added.
Best wishes for children were also expressed on Twitter by Deputy Prime Minister and Culture Minister Piotr Gliński. (PAP)
