7.5 month old waking every 10-15 minutes during the night

[pinkdreams]

My dd was text book until 6 months. Before six months she was sleeping a 6-7 hour stretch without feeding. Once she hit 6 months everything went downhill and continues to get worse sleepwise. For the past 3 nights, during 1-5 am she is getting up every 10-15 minutes and sitting up. I pat her and shush her, she lays back down and the whole thing repeats. She takes her naps like clockwork. Her is her schedule:

7:30- 8:00 - Wakes
10:00-11:30 morning nap
2:30 - 4:00-4:30 afternoon nap
6:30-7:00 catnap (I'm trying to drop this)
8:30-9:00 down for the night

Last night I pushed her past the catnap and put her down for the night at 7:20. She woke up screaming at 8:00. I shushed and gave her a binky. She slept again until 8:30 at which point she woke up and wanted to eat. I gave her a bottle and she was asleep again at 9:30. She woke up at 10:00 crying. I shushed she went right back to sleep. Woke up at 10:30 crying. I shushed she went right back to sleep. Slept until 1:30. She drank 4 ounces went back to sleep for 10-15 minutes. Then started the cycle of waking up every 10-15 minutes. I shush her and she goes right back to sleep. She did this until about 5:30 and then slept solid until 7:30. HELP!!

What are you doing to get rid of the cat nap?  Just trying to skip it?  You need to keep your A times relatively consistent (depending a bit on your LO, some of them like longer or shorter first A times) -- but average A time at 7.5 months is getting towards 3 hours so I'm wondering if that first A time needs to be longer.  You might get a longer nap out of that (closer to 2 hours) -- which when you put it together would let you drop the CN and still have an A time to bed in line with your other ones.  Those wakings right after BT sound like overtired wakings, but you do sound like you need to drop the cat nap to get her sleeping better at night so I'd start with the first A time and go from there.
