most of your routine looks fine, however the short naps jump out at me. 30/35min naps usually mean OT, 45/50min naps UT.
hunter's day at 9mths looked similar regarding bottle/eat times, however he was taking 2 naps about 1hr15 to 1hr30min.
regarding the 10.30 bottle, signs that they are ready to drop it can be taking less milk at this feed and/or the early arvo feed.
