Denver Zoo babies grow up fast as we pause to appreciate them in this photo essay.

On March 25, 2018, the zoo's clan of critically endangered Sumatran orangutans increased by one with the birth of Cerah (Che-rah), meaning "bright" in Indonesian. She's pictured with her mother, Nias (Nee-uhs). 

After some early health struggles, Dobby the giraffe was out and about in the first photo. When he reached his first birthday in February 2018, he measured 9 feet 6 inches tall. Denver Zoo threw a special birthday party for him and invited the public.

A few weeks before, the zoo welcomed its first birth of 2018, a female two-toed sloth named Baby Ruth. She's pictured below with her mother, Charlotte.

And in November 2017, Tilly, an endangered African wild dog, gave birth to four pups. Nigel, Roosevelt and Theodore, along with their sister, Cholula, recently made their public debut.  

"Denver Zoo is not only committed to helping wild babies here thrive but also around the world in their natural habitats. In fact, we commit over $2.2 million each year in people and resources to help protect wild animals and wild places," says Marie Revenew, vice president of external relations. "Come visit Denver Zoo and see amazing animals while helping to protect wildlife around the globe."

The zoo is open every day and is home to more than 4,000 animals, from Asian elephants to Komodo dragons.
