11 month old waking at night in the first hour after he goes down. Help!

This is very strange, and it is something that my 11 month old has done about 80% of his life!  It's my second child, and I never had this problem with the first.  I have the exact same nighttime routine with him every night, including giving him a bottle right before bed, after burping him.  He goes right down without a fuss (I lay him down drowsy but not asleep) around 7-730p, and within the hour, he's awake crying.  When we get him to sleep the second time, he ALWAYS sleeps until around 8am. 
His naps during the day are 45 min - 1 hour, and sometimes I cannot get him down for an afternoon nap, so he only takes one, which doesn't seem like enough.  He is close to walking, and FULL of energy, happy most of the time, and hardly shows signs of tiredness.  So my problem is 2-fold:
1)  The night waking after an hour of sleep
2)  Is one nap a day enough?

Hi there, normally waking in the early evening is a sign that he is OT from his day.  So it's likely that 1 nap may not be enough for him, especially given that it is quite short.  Some LO's would be able to cope a few days on 1 shorter nap but then they crash and burn so to speak and you start to get early evening wakings, NW and sometimes EW.

I would suggest that he still needs two naps, a short morning nap and then a longer PM nap - around 1.5-2 hrs.  The key is the right amount of A time between the 2 naps.

Can you post his day and we can take a look.
