From memory (like it was sooooo long ago ) Izzy was in a similar routine to now. Up anywhere from 630-8, up for 2 hours (at 5 mths it was more like about 1 1/2 hours) then down for a nap. So generally 3 naps a day. She was feeding about 2 1/2 -3 hourly too although she does go through phases of feeding more frequently at times, hot days, when shes started doing something new - like rolling etc. or if shes feeling grizzly. I do a feed/play/sleep routine although sometimes its more like play/feed/play/sleep!

I found about 3 -4 weeks ago that keeping her up for 2 hours meant she settled quicker for her naps and she sleeps for 1-2 hours at every nap now. At least one nap each day is 2 hours long.
Her bedtime is usually around 7-730! Good luck!
