Kids โ€” they grow up so fast! Why, it was just the other day that Baby Nero, the Maryland Zooโ€™s ridiculously cute baby lemur, was clinging to his motherโ€™s stomach, unable to get around on his own. Now that heโ€™s three months old, though, Nero spends more time riding around on his momโ€™s back โ€” when heโ€™s not jumping, bouncing, and climbing.

โ€œNero is becoming more and more independent,โ€ zoo officials say โ€” and do we detect a note of nostalgia in their voice? If you need video proof that Nero has lost none of his adorable-ness, watch a video of him scampering around here:

Nero is the youngest member of the zooโ€™s family of Coquerelโ€™s sifaka, an endangered species of lemur native to Madagascar. His mom, Anastasia; father, Gratian; and brother, Otto can be found in the zooโ€™s chimpanzee forest exhibit.
