How is she when she wakes at night? Crying or just fussy? Does she seem hungry?
I would also look at an earlier bedtime as her catnap ends at 4:45pm & the last A time is usually shorter than other A times so it could also be that she is awake for too long before bedtime (close to 3hrs... which is too long for her age) & therefore the nightwakings. I would look at bedtime around 7pm so that she is asleep around 7-7:15pm
Also you might want to start looking at 4hr EASY so that feeds are 4hrs apart & she takes more in at each feed. Try adding 15mins or so to her feeding time so she is not stretching the whole hour at once...
So something like this:
7am - wake & feed
9-10.30/11 - morning nap
11am - feed
12.30/1-2.30/3pm - afternoon nap (if the morning nap is only 1hr long then the afternoon nap would start around 12pm)
3pm - feed
4:30/5-5:15/5:45pm - catnap (if the morning nap was only 1hr & the afternoon nap was from 12-2 then catnap would be around 4pm as it is at the moment)
7-7:30pm - feed & bedtime (if the catnap ended around 5pm then bedtime no later than 7pm... to be asleep by 7pm that is. If catnap ended close to 6pm then bedtime can be later so around 7.30pm)
11pm - dreamfeed
hth & hope I didn't confuse you too much
Let me know how things are going
