What's happened???

Hoping someone can help.
Within the past week my almost 11 month DS has gone from sleeping 2-2.5 hrs during the day to sleeping 1 hour if I'm lucky. We used to be able to put him down for a nap in the morning and after lunch with no problems - a dummy and his stuffed monkey and he'd be off within minutes, sleeping nearly an hour in the morning and 1.5 or 1.75 hrs in the afternoon. Now as soon as I leave the room he pops back up screaming. I've tried staying in the room with him but he just goes on and on and I don't see the point in letting him cry so I just get him back out and let him play. Its starting to affect his nights now - he used to sleep between 11-12 hours soundly, now he wakes every few hours and cries a few minutes before going back to sleep. And wakes early at around 6:30am - he used to wake after 7.
He falls asleep now either in the pram, or sitting in the living room - he's so exhausted poor thing.
I tried cutting out his morning nap today thinking it would improve things - he slept exactly 40 minutes after lunch then was up screaming. I even tried rocking him back to sleep but he was just so upset. What's wrong?? This past week my sister was visiting from Canada and that was the only difference. Also, the nanny starts next week - maybe he senses my anxiety?? I've had a cry over this this morning (silly I know) b/c I just don't want him to be this unhappy when the Nanny is here.
Help!

i have an 11 month old (dd) and personally i wouldnt give in during the day, if he crys when you put him down for the lunch nap then keep going in to give him a dummy and walk out as you would do at 2am. (you dont get him up to play in the night so treat the daytime the same)

is the room dark enough? (we had to put up a blackout blind plus curtains and a thick black sheet)

he could just be a baby that just doesnt need that much sleep but then if hes waking in the night he might be overtired or could be teething?
dd2 is teething at the mo and she's waking for up to 2 and a hlaf hours in the night, she's off her food and generally not happy. we're giving her medised (when she'll have it!) and nurofen plus teething gel and powders!

its so hard at this age because they know what they want but cant communicate it to you.

Thanks for replying.
He seems to be better today - I put him down for both naps no problem - although he went down an hour later than usual for both naps. Maybe the problem was as simple as that?
Who knows! I'm learning that sometimes you just have to go with the flow.

I think he was waking in the night b/c he was overtired - he'd cry out but not totally wake up - and then when I'd go check on him he'd be fast asleep. Just a restless sleep.
Anyway, now that he's slept better today I'm hoping tonight he'll sleep better also.
