Hi Mel, here's my 9mth old DD's routine. Like your boy, she was having 4 bottles roughly 4 hourly and 3 solids and since 8 mths old she's on 3 bottles and 3 solids. She also goes to bed at about 7.30, but she does wake at 6.30 am, which is great on weekdays but seems ridiculously early when I want a weekend lie-in!

6.30am - wake up and bottle
7.30am - breakfast
8am - sleep
11am - lunch
1pm - sleep
2.30pm - bottle
5/5.30pm - dinner (we were feeding her at 6.30 when the rest of us eat, but she seems to get hungry by 5)
7pm - bottle
7.30pm - bed

In reality, it's only the 6.30 wake-up that actually happens at that time every day (I'm sure DD has a built-in alarm clock), everything else is roughly around the times I've put.
btw, when DD was having 4 bottles, they were at 6.30, 10.30, 2.30 and 7. So I've kind of replaced the 10.30 bottle with an 11 o'clock lunch and give her more brekky to keep her belly happy until then.

I hope this helps.
