Someone Help!

OK - yesterday he missed his day sleep just because we were out and about...we got him down as early as we could - about 7.15pm and then even though he was pretty cranky he went to sleep in 2 min.
Now today he zonked it and had a 2 1/2 hour sleep and was up before 3pm and it's now 8.20 and he's still mucking around - grrrr!!!!
So do I try to skip his sleep or do I wake him early??

Some more replies would be great!!! Thanks in advance!
