BRUGELETTE, Belgium — The two twin pandas babies, born in early August in the Belgian zoo of Pairi Daiza, have just celebrated their first month of existence, while the caretakers continue to monitor their health.

"Yesterday, the pandas turned one month. It's going so fast! And today we had the male in the incubator, the male weighed 1.4 kilos. Two days ago, we weighed the little female, and she was already 1.2 kilos, so they are gaining a lot of weight,"  Tim Bouts, zoological director at Pairi Daiza animal park said.
