Is your DD still having short naps? If so, is she having a feed around 4am? I did a lot of reading around this site and found that this may contribute to OT in the AMs, leading to the short nap cycle. (see the story about Josie's family under FAQ) Apparently babies do not get back into deep sleep after this feed, so they start the day OT. Today I snuck into DS's room at the 38 minute mark and HTTJ and covered his eyes, and we ended up with a 2 hour nap! I did the same for the next two naps after such a great AM nap, and during the second nap he didn't even flinch at the 45 minute mark. He was much more pleasant during the evening too! Now we'll see how he sleeps tonight...I think it takes a few days to break the cycle, and it is also recommended to drop the NF. (Don't know that this will work for us, as DS doesn't care to eat much). Hope this helps.
