This is the adorable moment two-year-old twin toddlers struggled to stay awake while drinking milk before taking an afternoon nap at a nursery in Loei, northeastern Thailand.

Babysitter Suputtra Promjai recorded sleepy young lads named Cue and Camp nodding off while sucking their feeding bottles while sitting together.

Supattra said: "They told me that they did not want to sleep, but look at their heavy eyes, they look so adorable."

The clip was filmed on July 10.
