What does an hour long sleep mean?

[ecwinters]

Hi
I'm slowly starting on transitioning DS from 2 naps to 1.  I've capped the first nap at 1 sleep cycle. So I have:

WU: Any time from about 5:30 but can be as 'late' (!!) as 6:00/6:15.  I don't get him up until 6:15.
Nap 1: 9:30-10:15 (sometimes he wakes up, or I wake him!) 
Nap 2: 14:00-15:00 (he pretty much wakes at the hour mark all the time - sometimes will doze off for a bit longer after a couple of minutes but I would love to get a solid 1:20-30 nap from him - he used to do this!)
Bedtime: 6:30 ish - depends when he woke from his 2nd nap.  He's normally asleep by 7 anyway.

If anyone has any thoughts then I'd be very grateful!  I know the next bit is to cap nap 1 further but I'm worried about him not extending nap 2 to compensate and then losing out on sleep.  We had to cap nap 1 to 45 minutes (I used to give him an hour) as he was playing around massively for nap 2 and then bedtime got really late - but he still woke early.

Does waking at the hour mean anything?! 

Thanks so much.

Hi there how old is he?

Is he an independent sleeper?

[ecwinters]

He was 16 months yesterday.  He's a great independent sleeper - can self settle and resettle both at night and for naps and generally loves his bed (must get that from me!).  I think he sees it as a place to chill out as well as sleep

For us at that age an hour nap was usually developmental or illness coming.

It's great he loves his bed

I think it was illness (he got a virus the day after posting this) but I think it's probably developmental also.  Two 1-hour sleeps are sometimes just what he does at the moment.
Thanks.
