For the last month, (well, really always) our afternoon nap has been hell. I spend 2-4 hours getting him to go to sleep and he sleeps for 30 minutes and wakes up screaming because he is so tired. I have tried leaving him, which used to work most days and he would go back to sleep, the last two weeks, he starts crying so hard he is choking, so I go get him, try to rock him back to sleep, but it rarely works. I have tried EVERYTHING except leaving him to CIO for an hour like Healthy Sleep Habits suggests. Anyway, I was telling a friend about it and she says her kids were just taking one afternoon nap at this age (7 months next week) and I should drop the morning nap. Is this really going to work? He starts getting cranky and 1.5/2 hours after waking up and goes down. How is he going to make it 5-6 hours? Is anyone's baby on this schedule. Her kids go to Kindercare and she says this is how they do it there. 
                
                             
        
Re: 7 months- one nap a day?
Our DD has nights like this and I conap with her (to get her to sleep if I cant sacrifice the time but I love when I can) and she goes out like a light and sleeps about an hour or two. She sleeps in her crib at night just fine though
Try what I said and try what your friend said see what works, its any port in the storm time. GL
We are having the exact same issue with both DD and DS. It takes about 30-40 minutes to get them to sleep and they wake up after 20-40 minutes. It is almost not worth it. I read in the Babies First Year Week by Week book that some babies move to only one nap around 7 months! Ha! I don't believe that. Ours are exhausted 2-3 hrs after waking... ugh!
I don't know what to do either and sorry to say I don't have any advice. I just wanted to let you know that you aren't alone! GL mama - hang in there!
