Just recently my DS has only been having 2 small (30-40 min) sleeps a day. Before this he was having a 40 min - 1 hour sleep, and a 1.5 hour sleep a day.

He seems happy enough straight after he wakes up, but then it doesn't take long for him to start looking tired again.

He is able to stay awake for longer periods, so I guess I'm wondering if maybe I should try keeping him up longer in the hopes that he'll have a longer sleep that actually refreshes him properly.

When did you LO go down to one sleep a day?
