UGH!!!!

I'm annoyed because:

Every_single_morning, IV and EL decide they prefer to nap only 45 minutes. Time lost is definitely NOT made up during afternoon siesta. They're up there squawking right now and it doesn't matter how long I let them do it - they don't go back to sleep. I wish I could separate them, but there isn't an inch of extra space in the house.

Not sure what to do and suggestions are welcome...
